------------------------------------

             Summary: Javadoc: Document that HBaseAdmin.flush(...) is 
synchronous
                 Key: HBASE-9266
                 URL: https://issues.apache.org/jira/browse/HBASE-9266
             Project: HBase
          Issue Type: Bug
            Reporter: Lars Hofhansl
            Priority: Trivial
             Fix For: 0.98.0, 0.94.12, 0.95.3


Currently the Javadoc in HBaseAdmin.flush(...) says that this is an 
asynchronous operation. Looking at the, however, it is in fact not.

Having this as a synchronous operation open ups some use cases we're interested 
in. For example doing some ingest via the high level API with WAL disabled and 
then issue a flush through the HBaseAdmin. When the flush succeeded we know the 
data is securely in HBase.
(This should work even with intermediary splits, as they also force a flush, 
but that needs to be verified as well.

So this is just for a trivial Javadoc change.
