[jira] Created: (HDFS-1244) Misc improvements to TestFileAppend2
Misc improvements to TestFileAppend2
------------------------------------
Key: HDFS-1244
URL: https://issues.apache.org/jira/browse/HDFS-1244
Project: Hadoop HDFS
Issue Type: Test
Components: test
Affects Versions: 0.20-append, 0.22.0
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Minor
Fix For: 0.20-append, 0.22.0
Attachments: hdfs-1244-0.20-append.txt
I've made a bunch of improvements to TestFileAppend2:
- Now has a main() with various command line options to change the workload (number of DNs, number of threads, etc)
- Sleeps for less time in between operations to catch races around close/reopen
- Updates to Junit 4 style, adds timeouts
- Improves error mesages on failure

[jira] Commented: (HDFS-1244) Misc improvements to TestFileAppend2

Todd Lipcon commented on HDFS-1244:
-----------------------------------
As an example, I have a hudson job running:
HADOOP_OPTS=-ea HADOOP_ROOT_LOGGER=DEBUG,console bin/hadoop org.apache.hadoop.hdfs.TestFileAppend2 --numDataNodes 1 --numThreads 40 --appendsPerThread 2000 --numFiles 1
HADOOP_OPTS=-ea HADOOP_ROOT_LOGGER=DEBUG,console bin/hadoop org.apache.hadoop.hdfs.TestFileAppend2 --numDataNodes 2 --numThreads 40 --appendsPerThread 2000 --numFiles 1
and it's found a couple of bugs in the 20 append function.
