stack resolved HBASE-12733. --------------------------- Resolution: Won't Fix Resolving won't fix. Old issue in a location that has undergone a bunch of refactoring since original filed. If someone has later evidence, lets reopen. > High volume of "Couldn't find oldest seqNum" warnings if bypassing WAL > ---------------------------------------------------------------------- > > Key: HBASE-12733 > URL: https://issues.apache.org/jira/browse/HBASE-12733 > Project: HBase > Issue Type: Bug > Reporter: Andrew Purtell > Priority: Minor > Labels: beginner > > When ingesting with the WAL bypassed, the RegionServer will log the following > at every flush: > {noformat} > 2014-12-19 16:58:24,630 WARN [MemStoreFlusher.0] wal.FSHLog: Couldn't find > oldest seqNum for the region we are about to flush: > [86fc8c1374ebc29cc4a39a78966d48e0] > {noformat} > The WAL won't find a seqnum for the region until the first edit which does > not bypass the WAL. That might not be for hundreds or thousands of flushes. > This shouldn't be at WARN level since ingest with WAL bypass is legal if a > bit unusual. It's concerning that the FSHLog code that emits that warning has > a TODO above suggesting the warning should instead be an assertion. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
