imbalance in HDFS with heterogeneous storages > ----------------------------------------------------- > > Key: HDFS-9608 > URL: https://issues.apache.org/jira/browse/HDFS-9608 > Project: Hadoop HDFS > Issue Type: Bug > Affects Versions: 2.6.0 > Reporter: Wei Zhou > Assignee: Wei Zhou > Attachments: HDFS-9608.01.patch, HDFS-9608.02.patch, > HDFS-9608.03.patch, HDFS-9608.04.patch > > > Currently RoundRobinVolumeChoosingPolicy use a shared index to choose volumes > in HDFS with heterogeneous storages, this leads to non-RR choosing mode for > certain type of storage. > Besides, it uses a shared lock for synchronization which limits the > concurrency of volume choosing process. Volume choosing threads that > operating on different storage types should be able to run concurrently. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
