Andrew Purtell updated HBASE-15866:
-----------------------------------
    Attachment: HBASE-15866.patch

Patch for master rebased on recent changes. 

Reviewboard: https://reviews.apache.org/r/50869/

Also fixes TestHCM#testCallableSleep

The following methods are *added* to Table:
{code}
int getReadRpcTimeout();
void setReadRpcTimeout(int readRpcTimeout);
int getWriteRpcTimeout();
void setWriteRpcTimeout(int writeRpcTimeout);
{code}

The following methods are *deprecated* in Table:
{code}
int getRpcTimeout();
void setRpcTimeout(int rpcTimeout);
{code}

This change targets master, branch-1, and 0.98.

In 0.98, we will not be changing HTableInterface but will be adding the new 
methods to HTable.

> We have a single tunable for the RPC timeout interval - hbase.rpc.timeout. 
> This is fine for the general case but there are use cases where it would be 
> advantageous to set two separate timeouts for reads (gets, scans, perhaps 
> with significant server side filtering - although the new scanner heartbeat 
> feature mitigates where available) and mutations (fail fast under tight SLA, 
> resubmit or take mitigating action). 
> I propose we refer to a configuration setting "hbase.rpc.read.timeout" when 
> handling read operations and "hbase.rpc.write.timeout" when handling write 
> operations. If those values are not set in the configuration, fall back to 
> the value of "hbase.rpc.timeout" or its default. 
> So for example in HTable instead of one global timeout for each RPC 
> (rpcTimeout), there would be a readRpcTimeout and writeRpcTimeout also set up 
> in HTable#finishSetup. Then wherever we set up RPC with 
> RpcRetryingCallerFactory#newCaller(int rpcTimeout) we pass in the read or 
> write timeout depending on what the op is.
> In general I don't like the idea of adding configuration parameters to our 
> already heavyweight set, but I think the inability to control timeouts 
> separately for reads and writes is an operational deficit.
