[jira] [Commented] (HBASE-27732) NPE in TestBasicWALEntryStreamFSHLog.testEOFExceptionInOldWALsDirectory
[ https://issues.apache.org/jira/browse/HBASE-27732?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17702119#comment-17702119 ]
Duo Zhang commented on HBASE-27732:
-----------------------------------
The error is
{noformat}
2023-03-17T03:42:54,025 WARN [Listener at localhost.localdomain/33967] wal.AbstractFSWALProvider(418): Cannot parse a server name from path=hdfs://localhost.localdomain:43341/home/jenkins/jenkins-home/workspace/HBase-Flaky-Tests_master/hbase-server/target/test-data/2f21d1db-c0f9-6ebc-17f1-124f110a5427/WALs/testEOFExceptionInOldWALsDirectory_1_ isCompressionEnabled=true]/testEOFExceptionInOldWALsDirectory_1_+isCompressionEnabled%3Dtrue%5D.1679024573986; null
{noformat}
I think first we need to find out the reason why it can not parse, and second we should guard against this error so at least usrs can know the reason is parsing server name error, instead of getting a runtime exception.
