Subject [jira] [Commented] (HBASE-13916) Create MultiByteBuffer
Date Tue, 16 Jun 2015 16:42:01 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13916?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14588346#comment-14588346

Anoop Sam John commented on HBASE-13916:
----------------------------------------

bq.-1 javac. The applied patch generated 15 javac compiler warnings (more than the master's
current 9 warnings).
bq.-1 javadoc. The javadoc tool appears to have generated 4 warning messages.
These are because of the usage of Unsafe in ByteBufferUtils.  We will have to add these counts
to the approved counts.

> This is an aggregation of N ByteBuffers. The block when served directly by block cache
buckets memory, we have the block data split across multiple byte buffers. This aggregate
type (like ByteBuffer) will serve the HFileBlock data.
> This jira wil just provide the new data structure
