[jira] [Commented] (HBASE-8615) HLog Compression fails in
mysterious ways (working title)
[ https://issues.apache.org/jira/browse/HBASE-8615?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13732832#comment-13732832 ]
Sergey Shelukhin commented on HBASE-8615:
-----------------------------------------
Could it be similar issue to HBASE-8498?
bq. The cause for this issue is that there's seems to be one case where we clean the compression context in the middle of reading a file
Is this a statement based on observation (then it would invalidate my comment)?
