<span style="box-sizing: border-box;">It implies, that Sentry is expecting its server name to be <span style="box-sizing: border-box; color: #777777;">HS2 </span>by default.

<div style="box-sizing: border-box; line-height: 1.4; margin-bottom: 1em; margin-left: 80px; margin-top: 1em; padding: 0px;">
Ensure that, the same is reflected in <span style="box-sizing: border-box; font-family: "courier new", courier, monospace;">sentry-site.xml</span> in <span style="box-sizing: border-box; font-family: "courier new", courier, monospace;">/etc/sentry/conf/sentry-site.xml </span>on the host where Sentry is installed.

<div style="text-align: justify;">
<b> <a href="http://fkrt.it/fG~lluuuuN">Apache Phoenix</a></b> is a relational database layer over HBase delivered as a client-embedded JDBC driver targeting low latency queries over HBase data. Apache Phoenix takes your SQL query, compiles it into a series of HBase scans, and orchestrates the running of those scans to produce regular JDBC result sets. The table metadata is stored in an HBase table and versioned, such that snapshot queries over prior versions will automatically use the correct schema. Direct use of the HBase API, along with coprocessors and custom filters, results in performance on the order of milliseconds for small queries, or seconds for tens of millions of rows.</div>

Once you clear the 2/3 telephonic rounds they will invite you for in-house interviews ( F2F or Video conference ) to the nearest amazon office .<br />
<br />
You will meet with 5-6 Amazonians. The mix of interviewers will include managers and peers that make up the technical team.<br />
<br />
Each meeting will be one-on-one interview sessions lasting approximately 45-60 minutes ( approx 5 hrs).<br />
<br />
In my case it was a video conference round , below are few behavioral questions covered in all the <b>5 rounds .</b><br />
<br />
<br />
1) Why Amazon?<br />
2)What is your understanding about the role?<br />
3)What do you wish to change in your current environment?<br />
4)What is the customer interaction that you are most proud of?<br />
5)Describe me your most difficult customer interaction?<br />
6)Tell me about a time you made a significant mistake . What would you have done differently?<br />
7)Give an example of a tough or critical piece of feedback you received. What was it and what did you do about it?<br />
8)Describe a time when you needed the cooperation of a peer or peers who were resistant to what you were trying to do. What did you do? What was the outcome?<br />
9)Saw a Peer Struggling and what did you do to help?<br />
10)Give me an example of when you have to make an important decision in the absence of good data because there just wasn’t any. What was the situation and how did you arrive at your decision? Did the decision turn out to be the correct one? Why or why not?<br />
11)Tell me about a time you took a big risk. What was the situation?<br />
12)Give me an example of a time when you were able to deliver an important project under a tight deadline. What sacrifices did you have to make to meet the deadline? How did they impact the final deliverable s?<br />

<div>
<br /></div>
<div>
<br /></div>
<div>
<b>Cause</b> : </div>
<div>
when I cloned one of my Linux virtual machine. So the cloned machine was not able to detect the NIC and every time I tried to restart the network it was throwing this error</div>
<div>
<br /></div>
<div>
<br /></div>
<div>
<b>Solution</b>: </div>
<div>
<br /></div>
<div>
The MAC id details for the NIC card is stored in the below mentioned file which is automatically created every time the machine boots.</div>
<div>
<br /></div>
<div>
/etc/udev/rules.d/70-persistent-net.rules</div>
<div>
<br /></div>
<div>
If you open this file the contents would be like this</div>
</div>
<div>
<br /></div>
<div class="separator" style="clear: both; text-align: center;">
<a href="http://2.bp.blogspot.com/-CP_BiGM7j4I/VRJjhAiOJeI/AAAAAAAAApk/ry8TkhD52LQ/s1600/1.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://2.bp.blogspot.com/-CP_BiGM7j4I/VRJjhAiOJeI/AAAAAAAAApk/ry8TkhD52LQ/s1600/1.png" height="57" width="640" /></a></div>
<div>
<br /></div>
<div>
Delete this file</div>
<div>
<br /></div>
<div>
rm -f /etc/udev/rules.d/70-persistent-net.rules</div>
<div>
<br /></div>
<div>
Reboot the machine i.e init 6</div>
<div>
<br /></div>
<div>
Now we can see difference in MAC id and NIC card name</div>
<div>
<br /></div>

<div style="text-align: left;">
</div>
<ul style="text-align: left;">
<li><b>OpenStack Swift</b>, also known as OpenStack Object Storage, is an open source object storage system that is licensed under the Apache 2.0 license and runs on standard server hardware.</li>
</ul>
<ul style="text-align: left;">
<li>OpenStack Swift is best suited to backup and archive unstructured data, such as documents, images, audio and video files, email and virtual machine images.</li>
</ul>
<ul style="text-align: left;">
<li>Objects and files are written to multiple drives, and the Swift software ensures the data is replicated across a server cluster. By default, Swift places three copies of every object in as unique-as-possible locations -- first by region, then by zone, server and drive. </li>
</ul>
<ul style="text-align: left;">
<li>If a server or hard drive fails, OpenStack Object Storage replicates its content from active nodes to new locations in the cluster. </li>
</ul>
<ul style="text-align: left;">
<li>The system, which is accessed through a REST HTTP application programming interface (API), can scale horizontally to store petabytes of data through the addition of nodes, which typically equate to servers. OpenStack Swift software is based on Cloud Files technology developed by Rackspace Hosting Inc. </li>
</ul>
<ul style="text-align: left;">
<li>Rackspace and NASA initiated the project and co-founded the community that develops and maintains OpenStack software, which includes compute, storage and networking components for building cloud computing services.</li>
</ul>

<span class="Apple-tab-span" style="white-space: pre;"> </span>Exposes the public API<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span><br />
2.Ring<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Maps names to entities (accounts, containers, objects) on disk.<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Stores data based on zones, devices, partitions, and replicas<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Weights can be used to balance the distribution of partitions<br />
<span class="Apple-tab-span" style="white-space: pre;"> </span>Used by the Proxy Server for many background processes<br />
3.Object Server<br />

Swift & Large Object Storage:<br />
==============================<br />
<br />
Default 5GB limit on the size of an uploaded object<br />
Segmentation makes download size of a single object is virtually unlimited<br />
Segments large object are uploaded and a special manifest file is created when downloaded, all segments are concatenated as a single object.<br />
Greater upload speed<br />
Possible parallel uploads of segments.<br />
<br />
Swift Components:<br />
=================<br />
<br />
Replication<br />

<br />
Updaters<br />
Process failed or queued updates<br />
<br />
Auditors<br />
Verify integrity of objects, containers, and accounts<br />
<br />
Container Server:<br />
Handles listing of objects, stores as SQLite DB<br />
<br />
Account Server:<br />
Handles listing of containers, stores as SQLite DB<br />
<br />
Limitation:<br />
===========<br />
