The checkstyle warning is due to number of parameters and mot much can be done

[jira] [Commented] (YARN-3841) [Storage implementation] Adding retry semantics to HDFS backing storage

2018-09-06 Thread Vrushali C (JIRA)

Thanks [~abmodi] ! Patch looks good overall. A couple of minor comments:

- let's use File.separator instead of an actual "/" 

- For FileSystemTimelineWriterImpl.java, I think we may not want to do a   
fs.close(); at line 261. This will close the FileSystem handle for all threads 
in that process since this is a static instance. 

-  For line281, instead of 
 {{monospaced}} LOG.info("Retrying operation on FS. Retry no. " + retry); 
{{monospaced}}
we could perhaps update it to 
 {{monospaced}}  "Will retry operation on  FS. Retry no. " + retry + " after 
sleeping for " + fsRetryInterval + " seconds" );  {{monospaced}} 

Will be a better indication of the sleep & retry. What do you think?

Hi [~gtCarrera9] [~ozawa],

At our company, we used HDFS as storage for trying out ATSv2. If it's fine for 
you, can I create a new patch on top of YARN-7055 branch. Thanks.

[~ozawa] we have closed the work on the alpha-1 branch (which [~sjlee0] merged 
to trunk over the weekend).
We'll continue our work on YARN-5355. I've moved this jira over.
Patches for this jira will be named YARN-3841-YARN-5355.02.patch
