Ted Yu created HBASE-16672: ------------------------------ Summary: Add option for bulk load to copy hfile(s) instead of renaming Key: HBASE-16672 URL: https://issues.apache.org/jira/browse/HBASE-16672 Project: HBase Issue Type: Improvement Reporter: Ted Yu
While working on HBASE-14417, I found that taking full backup of table which received bulk loaded hfiles and later gone through incremental restore failed with the following exception: {code} 2016-09-21 11:33:06,340 WARN [member: '10.22.9.171,53915,1474482617015' subprocedure-pool7-thread-1] snapshot.RegionServerSnapshotManager$SnapshotSubprocedurePool(347): Got Exception in SnapshotSubprocedurePool java.util.concurrent.ExecutionException: java.io.FileNotFoundException: File does not exist: hdfs://localhost:53901/user/tyu/test-data/48928d44-9757-4923-af29-60288fb8a553/data/ns1/test-1474482646700/ d1a93d05a75c596533ba4331a378fb3a/f/3dfb3a37cf6b4b519769b3116d8ab35a_SeqId_205_ at java.util.concurrent.FutureTask.report(FutureTask.java:122) at java.util.concurrent.FutureTask.get(FutureTask.java:192) at org.apache.hadoop.hbase.regionserver.snapshot.RegionServerSnapshotManager$SnapshotSubprocedurePool.waitForOutstandingTasks(RegionServerSnapshotManager.java:323) at org.apache.hadoop.hbase.regionserver.snapshot.FlushSnapshotSubprocedure.flushSnapshot(FlushSnapshotSubprocedure.java:139) at org.apache.hadoop.hbase.regionserver.snapshot.FlushSnapshotSubprocedure.insideBarrier(FlushSnapshotSubprocedure.java:159) {code} The cause was that the bulk loaded hfiles were renamed during bulk load step of incremental restore. To support incrementally restoring to multiple destinations, this issue adds option which would always copy hfile(s) during bulk load. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
