Rodrigo Schmidt updated HDFS-684: --------------------------------- Status: Patch Available (was: Open) > Use HAR filesystem to merge parity files > ----------------------------------------- > > Key: HDFS-684 > URL: https://issues.apache.org/jira/browse/HDFS-684 > Project: Hadoop HDFS > Issue Type: Improvement > Components: contrib/raid > Reporter: dhruba borthakur > Assignee: Rodrigo Schmidt > Attachments: HDFS-684.0.patch, HDFS-684.1.patch > > > The HDFS raid implementation (HDFS-503) creates a parity file for every file > that is RAIDed. This puts additional burden on the memory requirements of the > namenode. It will be nice if the parity files are combined together using > the HadoopArchive (har) format. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
