[ https://issues.apache.org/jira/browse/HBASE-6116?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Lars Hofhansl updated HBASE-6116: --------------------------------- Attachment: 6116-v1.txt Initial patch, which includes HBASE-5954. This also fixes building HBase trunk with Hadoop trunk (3.0.0-SNAPSHOT). In order to test, HDFS-1783 needs to be applied to Hadoop (trunk) first. Then build Hadoop with: mvn -Pnative -Pdist -Dtar -DskipTests install And then HBase with: mvn -DskipTests -Dhadoop.profile=3.0 ... Parallel writes can be enable in hbase-site.xml with: hbase.regionserver.wal.parallel.writes Since this patch include HBASE-5954, durable sync can also be enabled: hbase.regionserver.wal.durable.sync hbase.regionserver.hfile.durable.sync (all options can be set to "true") @Andy: If your offer to do a quick test in EC2 still stands that'd be awesome! > Allow parallel HDFS writes for HLogs. > ------------------------------------- > > Key: HBASE-6116 > URL: https://issues.apache.org/jira/browse/HBASE-6116 > Project: HBase > Issue Type: Bug > Reporter: Lars Hofhansl > Assignee: Lars Hofhansl > Attachments: 6116-v1.txt > > > In HDFS-1783 I adapted Dhrubas changes to be used in Hadoop trunk. > This issue will include the necessary reflection changes to optionally enable > this for the WALs in HBase. -- This message is automatically generated by JIRA.
