Last updated on OCTOBER 11, 2016
Applies to:Big Data Appliance Integrated Software - Version 3.0.1 and later
On Oracle Big Data Appliance(BDA) CDH Cluster after upgrade to 3.0.1 , previous directories from datanodes are NOT removed.
Due to this symptoms noticed an a BDA CDH Cluster are
1) Cloudera Manager will report HIGH DFS Space usage
2) Cloudera Manager HDFS Capacity and Cluster Disk usage Report will vary
3) Balancer running for a very long time and had to abort the Balancer after 48 hours.
4) Maybe some cases dfsadmin reports indicates one/more of the BDA nodes is 100% full where as on rest of the BDA nodes only 20% of Disk usage noticed
