> Make HDFS block size configurable for HBase WAL
> -----------------------------------------------
>
> Key: HBASE-6578
> URL: https://issues.apache.org/jira/browse/HBASE-6578
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Reporter: Karthik Ranganathan
> Assignee: Li Pi
>
> Right now, because sync-on-block-close is enabled, HLog causes the disk to
> stall out on large writes (esp when we cross block boundary).
> We currently use 256MB blocks. The idea is that if we use smaller block
> sizes, we should be able to spray the data across more disks (because of
> round robin scheduling) and this would cause more uniform disk usage.
