Attached is a stand alone utility to test compression compatibility

Hi,

Thanks for this. I found it very useful this morning. Can we get this included in the standard distribution?

For those not so familiar with building and running code against hbase, the following detailed steps may be useful,

1. Download compression test util from
http://mail-archives.apache.org/mod_mbox/hadoop-hbase-user/200909.mbox/%3C4AC272

2. Compile

(change .jar's below to match your hadoop and hbase versions)

javac -cp hadoop/hadoop-0.20.1-core.jar:hbase/hbase-0.20.0.jar HFileCompressionTest.java

3. "Install"
mkdir -p build/org/apache/hadoop/hbase/test
mv HFileCompressionTest.class build/org/apache/hadoop/hbase/test

4. Run
export HBASE_CLASSPATH=build
hbase/bin/hbase org.apache.hadoop.hbase.test.HFileCompressionTest hdfs://hbase.example.org:9000/ lzo
