Subject [jira] [Commented] (HBASE-14951) Make hbase.regionserver.maxlogs obsolete
Date Tue, 08 Dec 2015 22:57:10 GMT

    [ https://issues.apache.org/jira/browse/HBASE-14951?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15047636#comment-15047636

Vladimir Rodionov commented on HBASE-14951:
-------------------------------------------

The idea is to avoid premature memstore flush due to max log files. 32 is too small. Should
not be capped.

> There was a discussion in HBASE-14388 related to maximum number of log files. It was
an agreement that we should calculate this number in a code but still need to honor user's
setting. 
> Maximum number of log files now is calculated as following:
>  maxLogs = HEAP_SIZE * memstoreRatio * 2/ LogRollSize
