Nihal Jain updated HBASE-21672:
-------------------------------
Description:
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.
Currentlly, we do not have a way to skip hdfs block distribution computation.
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.
