Vinayakumar B commented on HDFS-8382:
-------------------------------------
[~drankye] and [~aw], I think the problem is, when the jenkins is running
*Precommit-HDFS-Build* on the branch HDFS-7285 with running hadoop-hdfs module
tests, it depends on hadoop-common and hadoop-hdfs-client module's jars present
in local maven repo.
At the same time, these jars can be replaced by another hadoop job of
*Precommit-HADOOP-Build* or any other Hadoop project running on different
branch.
So for the HDFS-7285's tests, extra classes added in same branch and in some
other module (hadoop-common/hadoop-hdfs-client) will be missing.
Till now we have seen failures with missing classes from hadoop-common and
hadoop-hdfs-client modules while running hadoop-hdfs tests.
I think the solution will be like having a separate maven repo for each jenkins
project to avoid the collisions, even though results in duplicate contents of
repo. What you say [~aw] ?
Similar problem would have been experienced earlier when the patch involved
multiple module changes.

> Per discussion in HDFS-8347, we need to support encoding/decoding variable
> width units data instead of predefined fixed width like {{chunkSize}}. Have
> this issue to remove chunkSize in the general raw erasure coder API. Specific
> coder will support fixed chunkSize using hard-coded or specific schema
> customizing way if necessary, like HitchHiker coder.
