[jira] Created: (HDFS-684) Use HAR filesystem to merge parity files
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
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.
