stack commented on HBASE-4908: ------------------------------ Backed out SequenceFileLogReader.java change -- will address in a way that doesn't break us going against 0.22 and 0.23 in HBASE-4935 > HBase cluster test tool (port from 0.89-fb) > ------------------------------------------- > > Key: HBASE-4908 > URL: https://issues.apache.org/jira/browse/HBASE-4908 > Project: HBase > Issue Type: Sub-task > Reporter: Mikhail Bautin > Assignee: Mikhail Bautin > Fix For: 0.94.0 > > Attachments: 0001-HBase-cluster-test-tool.patch, > 0002-HBase-cluster-test-tool.patch, 0003-HBase-cluster-test-tool.patch, > D549.1.patch, D549.2.patch, D549.3.patch, D549.4.patch, D549.5.patch, > D549.6.patch, D549.7.patch, D549.8.patch, D549.9.patch > > > Porting one of our HBase cluster test tools (a single-process multi-threaded > load generator and verifier) from 0.89-fb to trunk. > I cleaned up the code a bit compared to what's in 0.89-fb, and discovered > that it has some features that I have not tried yet (some kind of a kill > test, and some way to run HBase as multiple processes on one machine). > The main utility of this piece of code for us has been the HBaseClusterTest > command-line tool (called HBaseTest in 0.89-fb), which we usually invoke as a > load test in our five-node dev cluster testing, e.g.: > hbase org.apache.hadoop.hbase.manual.HBaseTest -load 1000000000:50:100:20 -tn > load_test -read 1:1000000000:50:20 -zk <zk_quorum> -bloom ROWCOL -compression > GZIP > I will be using this code to load-test the delta encoding patch and making > fixes, but I am submitting the patch for early feedback. I will probably try > out its other functionality and comment on how it works. -- This message is automatically generated by JIRA.
