            Description

            Multiple efforts have been made gradually to improve the CRC performance in Hadoop. This JIRA is to back port these changes to branch-1, which include HADOOP-6166, HADOOP-6148, HADOOP-7333.

            The related HDFS and MAPREDUCE patches are uploaded to their original JIRAs HDFS-496 and MAPREDUCE-782.
