----------------------------------
Summary: Reduce logging frequency of
QuorumJournalManager#selectInputStreams
Key: HDFS-13789
URL: https://issues.apache.org/jira/browse/HDFS-13789
Project: Hadoop HDFS
Issue Type: Improvement
Components: namenode, qjm
Affects Versions: HDFS-12943
Reporter: Erik Krogen
Assignee: Erik Krogen
As part of HDFS-13150, a logging statement was added to indicate whenever an
edit tail is performed via the RPC mechanism. To enable low latency tailing,
the tail frequency must be set very low, so this log statement gets printed
much too frequently at an INFO level. We should decrease to DEBUG. Note that if
there are actually edits available to tail, other log messages will get
printed; this is just targeting the case when it attempts to tail and there are
no new edits.
