Mathias Herberts updated HBASE-1770:
------------------------------------

    Attachment: setWriteBufferSize-flushCommits.patch

Adds call to flushCommits if the new size of the write buffer is lower than the current size of the data in the buffer.

Side effect is that setWriteBufferSize now throws IOException as propagated from flushCommits.

> When setting the size of the write buffer to a value lower than the current size of data in the write buffer, the content of the write buffer should be flushed so it does not occupy in memory more than its new size for an extended period of time.
