Kitti Nanasi commented on HDFS-13882:
-------------------------------------
Thanks for reviewing it [~shwetayakkali]!
I looked into the test failures and TestAddStripedBlocks#testAddUCReplica does
fail because patch v001, because in DFSOutputStream#completeFile the sleep time
between retries is multiplied by 2 at every attempt starting from 400 ms, and
now that the default number of retries has increased to 10, the waiting time
has increased too much. I will upload a patch which increases the sleep time at
every attempt with only the default delay.
The other tests doe not seem relevant to this modification and pass locally.
> Change dfs.client.block.write.locateFollowingBlock.retries default from 5 to
> 10

> More and more we are seeing cases where customers are running into the java
> io exception "Unable to close file because the last block does not have
> enough number of replicas" on client file closure. The common workaround is
> to increase dfs.client.block.write.locateFollowingBlock.retries from 5 to 10.
