---------------------------------
Summary: QJM: quorum timeout on failover with large log segment
Key: HDFS-3906
URL: https://issues.apache.org/jira/browse/HDFS-3906
Project: Hadoop HDFS
Issue Type: Sub-task
Affects Versions: QuorumJournalManager (HDFS-3077)
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Critical
In doing some stress tests, I ran into an issue with failover if the current
edit log segment written by the old active is large. With a 327MB log segment
containing 6.4M transactions, the JN took ~11 seconds to read and validate it
during the recovery step. This was longer than the 10 second timeout for
createNewEpoch, which caused the recovery to fail.
