New in CDH 5.4: Apache HBase Request Throttling

The following post about the new request throttling feature in HBase 1.1 (now shipping in CDH 5.4) originally published in the ASF blog. We re-publish it here for your convenience.

Running multiple workloads on HBase has always been challenging, especially  when trying to execute real-time workloads while concurrently running analytical jobs. One possible way to address this issue is to throttle analytical MR jobs so that real-time workloads are less affected.

Scan Improvements in Apache HBase 1.1.0

The following post, from Cloudera intern Jonathan Lawlor, originally appeared in the Apache Software Foundation’s blog.

Over the past few months there have a been a variety of nice changes made to scanners in Apache HBase. This post focuses on two such changes, namely RPC chunking (HBASE-11544) and scanner heartbeat messages (HBASE-13090). Both of these changes address long standing issues in the client-server scan protocol. Specifically, RPC chunking deals with how a server handles the scanning of very large rows and scanner heartbeat messages allow scan operations to progress even when aggressive server-side filtering makes infrequent result returns.
