Work Description: adoroszlai commented on pull request #120: HDDS-2407.
Reduce log level of per-node failure in XceiverClientGrpc
URL: https://github.com/apache/hadoop-ozone/pull/120
## What changes were proposed in this pull request?
When reading from a pipeline, client should not care if some datanode could
not service the request, as long as the pipeline as a whole is OK. The [log
message](https://github.com/apache/hadoop-ozone/blob/2529cee1a7dd27c51cb9aed0dc57af283ff24e26/hadoop-hdds/client/src/main/java/org/apache/hadoop/hdds/scm/XceiverClientGrpc.java#L303-L304)
indicating node failure was [increased to error
level](https://github.com/apache/hadoop-ozone/commit/a79dc4609a975d46a3e051ad6904fb1eb40705ee#diff-b9b6f3ccb12829d90886e041d11395b1R288)
in [HDDS-1780](https://issues.apache.org/jira/browse/HDDS-1780). This PR
proposes to change it back to debug. Pipeline-level failure is still logged as
error.
https://issues.apache.org/jira/browse/HDDS-2407

Tested locally on docker-compose cluster with 0/1/2/3 datanodes down.
