· HBASE_CHECKSUM_VERIFICATION
public static final StringHBASE_CHECKSUM_VERIFICATION
If thisparameter is set to true, then hbase will read data and then verify checksums.Checksum verification inside hdfs will be switched off. However, if thehbase-checksum verification fails, then it will switch back to using hdfschecksums for verifiying data that is being read from storage. If thisparameter is set to false, then hbase will not verify any checksums, instead itwill depend on checksum verification being done in the hdfs client.
