             Summary: Allow skipping HDFS block distribution computation
                 Key: HBASE-21672
                 URL: https://issues.apache.org/jira/browse/HBASE-21672
             Project: HBase
          Issue Type: Improvement
            Reporter: Nihal Jain
            Assignee: Nihal Jain


We should have a configuration to skip HDFS block distribution calculation in HBase. For example on file systems that do not surface locality such as S3, calculating block distribution would not be any useful, we should have a way to skip hdfs block distribution.

For this, we can provide a new configuration key, say {{hbase.block.distribution.skip.computation}}, which would be {{false}} by default. Users using filesystems such as s3 may choose to make this {{true}}, thus skipping block distribution computation.
