[jira] [Created] (HBASE-6578) Make HDFS block size configurable for
HBase WAL
Karthik Ranganathan created HBASE-6578:
------------------------------------------
Summary: 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
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.
