Hi, We are running hbase with application level checksums turned on. We basically have the following configuration:
dfs.client.read.shortcircuit.skip.checksum -> true hbase.regionserver.checksum.verify -> true We have shortcircuit reads enabled and have verified that its working - only the HBase region server is accessing the disk. However, an strace on the region server shows some mysterious 7 byte seeks on the .meta files (which are also supposed to contain the checksum). We are running hadoop-2.0.0-alpha. Do 7 byte reads from .meta files ring a bell to someone's ears - I am not totally sure if these are checksums or not and I also don't know enough about hdfs ? Thanks Varun
