Ayush Saxena commented on HDFS-14966:
-------------------------------------
Thanx [~zgw] for the report.
Seems not only negative but the block pool used and DFS Used is also coming
undefined.
Did you check the JMX values, for capacity used and capacity remaining, what
are they?
Did you check the Datanodes pages if storage stats are correct there?
Could be an issue with the Namenode calculating stats combining report from 10K
datanodes.
Any LOG evidences at the namenode?
Is the namenode able to perform all write operations?
> In NameNode Web UI, Some values are shown as negative
