Attila Doroszlai updated HDDS-3152:
-----------------------------------
Status: Patch Available (was: In Progress)
> Reduce number of chunkwriter threads in integration tests
> ---------------------------------------------------------
>
> Key: HDDS-3152
> URL: https://issues.apache.org/jira/browse/HDDS-3152
> Project: Hadoop Distributed Data Store
> Issue Type: Improvement
> Components: test
> Reporter: Attila Doroszlai
> Assignee: Attila Doroszlai
> Priority: Minor
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Integration tests run multiple datanodes in the same JVM. Each datanode
> comes with 60 chunk writer threads by default (may be decreased in
> HDDS-3053). This makes thread dumps (eg. produced by
> {{GenericTestUtils.waitFor}} on timeout) really hard to navigate, as there
> may be 300+ such threads.
> Since integration tests are generally run with a single disk which is even
> shared among the datanodes, a few threads per datanode should be enough.
