Description

HBASE-21034 provides a new throttle type: capacity unit, but the throttling exception is confusing: 

 

2018-12-11 14:38:41,503 DEBUG [Time-limited test] client.RpcRetryingCallerImpl(131): Call exception, tries=6, retries=7, started=0 ms ago, cancelled=false, msg=org.apache.hadoop.hbase.quotas.RpcThrottlingException: write size limit exceeded - wait 10sec
at org.apache.hadoop.hbase.quotas.RpcThrottlingException.throwThrottlingException(RpcThrottlingException.java:106)
at org.apache.hadoop.hbase.quotas.RpcThrottlingException.throwWriteSizeExceeded(RpcThrottlingException.java:96)
at org.apache.hadoop.hbase.quotas.TimeBasedLimiter.checkQuota(TimeBasedLimiter.java:179)

Need to make the exception more clearly.
