Hudson commented on HBASE-19732: -------------------------------- FAILURE: Integrated in Jenkins build HBase-Trunk_matrix #4407 (See [https://builds.apache.org/job/HBase-Trunk_matrix/4407/]) HBASE-19732 Replica regions does not return back the MSLAB chunks to (ramkrishna.s.vasudevan: rev d155a4e33d279bdf4b57b08ebc8220fe5d97f4cc) * (edit) hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HStore.java * (edit) hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/MemStoreSnapshot.java > Replica regions does not return back the MSLAB chunks to pool > ------------------------------------------------------------- > > Key: HBASE-19732 > URL: https://issues.apache.org/jira/browse/HBASE-19732 > Project: HBase > Issue Type: Bug > Affects Versions: 2.0.0-alpha-4 > Reporter: ramkrishna.s.vasudevan > Assignee: ramkrishna.s.vasudevan > Priority: Critical > Fix For: 2.0.0-beta-2 > > Attachments: HBASE-19732.patch, HBASE-19732_1.patch, > HBASE-19732_2.patch > > > When we have region replica enabled, we try to replicate the flush markers. > In the replica region on receiving the FLUSH_START_MARKER we create a > snapshot. On receiving COMMIT_FLUSH_MARKER we just update the store files and > clear the snapshot. But in the recent trunk code while creating snapshot > (need to verify in other branches too) > {code} > this.timeRangeTracker = snapshot.getTimeRangeTracker(); > this.scanners = snapshot.getScanners(Long.MAX_VALUE, Long.MAX_VALUE); > this.tagsPresent = snapshot.isTagsPresent(); > {code} > The scanners that we create internally increment the openScannerCount per > MSLAB. But since in this case we don't call scanner.close() we don't > decrement the scanner count and so the MSLAB chunks are not returned back to > the pool when the snapshot is closed in the replica region. > {code} > int count = openScannerCount.get(); > LOG.info("the count is "+count); > if(count == 0) { > recycleChunks(); > {code} > This is a critical bug. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
