-----------------------------
Summary: Failed effort upping default HDFS blocksize,
hbase.regionserver.hlog.blocksize
Key: HBASE-20520
URL: https://issues.apache.org/jira/browse/HBASE-20520
Project: HBase
Issue Type: Sub-task
Components: conf
Reporter: stack
Good one found by our [~mdrob]. Problem in the parent issue where failed
attempt doubling default block size but halving the size at which roll -- so we
end up in roughly same place only we make less small WALs in those cases where
we are writing furiously and fail to roll before starting a new block.
>From Drob: ".../we drop default log roll to 0.5, but we don't actually
>increase the block size... AbstractProtobufLogWriter.java:164 still uses
>default HDFS block sizing and AbstractFSWAL.java:408 block size is only used
>in a log message, never actually makes it to files...".
