HBase using its own checksum handling doesn't directly affect HDFS. It will
still maintain checksum info.  The diff is at the read time..  HBase will
open reader with checksum validation false and it will do checksum
validation on its own.   So using hbase handled checksum in a cluster
should not affect other data..  Does that solves your doubt?
