Rural Hunter created HBASE-10303:
------------------------------------
Summary: Have snappy support properly documented would be helpful
to hadoop and hbase users
Key: HBASE-10303
URL: https://issues.apache.org/jira/browse/HBASE-10303
Project: HBase
Issue Type: Task
Components: documentation
Reporter: Rural Hunter
The currentl document for configuring snappy
support(http://hbase.apache.org/book/snappy.compression.html) is not complete
and it's a bit obscure. IMO, there are several improvments can be made:
1. Describe the relationship among hadoop,hbase,snappy. Is the snappy actually
needed by hadoop hdfs or hbase itself? That's to make clear if you need to
configure snappy support in hbase or hadoop.
2. It didn't mention the default hadoop binary package is compiled without
snappy support and you need to compile it with snappy option manually. Actually
it didn't work with any native libs on 64 bits OS as the libhadoop.so in the
binary package is only for 32 bits OS(this of course is a hadoop issue not
hbase. but it's good to mention it.).
3. In my experience, I actually need to install both snappy and hadoop-snappy.
So the doc lack of the steps to install hadoop-snappy.
4. During my set up, I found difference where hadoop and hbase to pick up the
native lib files. hadoop picks those files in ./lib while hbase picks in
./lib/[PLATFORM]. If it's correct, it can also be mentioned.
