Ted Yu created HBASE-21381: ------------------------------ Summary: Document the hadoop versions using which backup and restore feature works Key: HBASE-21381 URL: https://issues.apache.org/jira/browse/HBASE-21381 Project: HBase Issue Type: Task Reporter: Ted Yu
HADOOP-15850 fixes a bug where CopyCommitter#concatFileChunks unconditionally tried to concatenate the files being DistCp'ed to target cluster (though the files are independent). Following is the log snippet of the failed concatenation attempt: {code} 2018-10-13 14:09:25,351 WARN [Thread-936] mapred.LocalJobRunner$Job(590): job_local1795473782_0004 java.io.IOException: Inconsistent sequence file: current chunk file org.apache.hadoop.tools.CopyListingFileStatus@bb8826ee{hdfs://localhost:42796/user/hbase/test-data/ 160aeab5-6bca-9f87-465e-2517a0c43119/data/default/test-1539439707496/96b5a3613d52f4df1ba87a1cef20684c/f/a7599081e835440eb7bf0dd3ef4fd7a5_SeqId_205_ length = 5100 aclEntries = null, xAttrs = null} doesnt match prior entry org.apache.hadoop.tools.CopyListingFileStatus@243d544d{hdfs://localhost:42796/user/hbase/test-data/160aeab5-6bca-9f87-465e- 2517a0c43119/data/default/test-1539439707496/96b5a3613d52f4df1ba87a1cef20684c/f/394e6d39a9b94b148b9089c4fb967aad_SeqId_205_ length = 5142 aclEntries = null, xAttrs = null} at org.apache.hadoop.tools.mapred.CopyCommitter.concatFileChunks(CopyCommitter.java:276) at org.apache.hadoop.tools.mapred.CopyCommitter.commitJob(CopyCommitter.java:100) at org.apache.hadoop.mapred.LocalJobRunner$Job.run(LocalJobRunner.java:567) {code} Backup and Restore uses DistCp to transfer files between clusters. Without the fix from HADOOP-15850, the transfer would fail. This issue is to document the hadoop versions which contain HADOOP-15850 so that user of Backup and Restore feature knows which hadoop versions they can use. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
