LiuLei created HBASE-6798:
-----------------------------
Summary: HDFS always read checksum form meta file
Key: HBASE-6798
URL: https://issues.apache.org/jira/browse/HBASE-6798
Project: HBase
Issue Type: Bug
Components: performance
Affects Versions: 0.94.1, 0.94.0
Reporter: LiuLei
I use hbase0.941 and hadoop-0.20.2-cdh3u5 version.
The HBase support checksums in HBase block cache in HBASE-5074 jira.
The HBase support checksums for decrease the iops of HDFS, so that HDFS
dont't need to read the checksum from meta file of block file.
But in hadoop-0.20.2-cdh3u5 version, BlockSender still read the metadata file
even if the
hbase.regionserver.checksum.verify property is ture.
