[jira] [Created] (HDFS-10722) Fix race condition in TestEditLog#testBatchedSyncWithClosedLogs

             Summary: Fix race condition in TestEditLog#testBatchedSyncWithClosedLogs
                 Key: HDFS-10722
                 URL: https://issues.apache.org/jira/browse/HDFS-10722
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs
            Reporter: Daryn Sharp
            Assignee: Daryn Sharp


The test may fail the following assertion if async edit logs are enabled:
{{logging edit without syncing should do not affect txid expected:<1> but was:<2>}}.  The async thread is doing batched syncs in the background.  logSync just ensures the edit is durable, so the txid may increase prior to sync.  It's a race.
