[jira] [Created] (HDFS-10309) HDFS Balancer doesn't honor
dfs.blocksize value defined with suffix k(kilo), m(mega), g(giga)
Amit Anand created HDFS-10309:
---------------------------------
Summary: HDFS Balancer doesn't honor dfs.blocksize value defined with suffix k(kilo), m(mega), g(giga)
Key: HDFS-10309
URL: https://issues.apache.org/jira/browse/HDFS-10309
Project: Hadoop HDFS
Issue Type: Bug
Components: balancer & mover
Affects Versions: 2.8.0
Reporter: Amit Anand
Assignee: Amit Anand
While running HDFS Balancer I get error given below when {{dfs.blockSize}} is defined with suffix {{k(kilo), m(mega), g(giga)}}. In my deployment {{dfs.blocksize}} is set to {{128m}}.

However, the workaround for this is to run {{hdfs balancer}} with passing numeric value for {{dfs.blocksize}}
{code}
hdfs balancer -Ddfs.blocksize=134217728
