Work on HDFS-8876 started by Chris Trezzo. ------------------------------------------ > Make hard coded parameters used by balancer and other tools configurable > ------------------------------------------------------------------------ > > Key: HDFS-8876 > URL: https://issues.apache.org/jira/browse/HDFS-8876 > Project: Hadoop HDFS > Issue Type: Improvement > Reporter: Ming Ma > Assignee: Chris Trezzo > > During investigation of how to speed up balancer, at least to the level > specified by {{dfs.datanode.balance.bandwidthPerSec}}, we found that > parameters such as {{MAX_BLOCKS_SIZE_TO_FETCH}} and > {{SOURCE_BLOCKS_MIN_SIZE}} are hard coded. These parameters are related to > block size and other configurable parameters used by balancer. So least we > should make it configurable. In the longer term, it might be interesting to > understand if we simplify all these related configurations. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
