Subject [jira] [Updated] (HBASE-10303) Have snappy support properly documented would be helpful to hadoop and hbase users
Date Fri, 10 Jan 2014 19:47:50 GMT

     [ https://issues.apache.org/jira/browse/HBASE-10303?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

stack updated HBASE-10303:

         Priority: Blocker  (was: Major)
    Fix Version/s: 0.96.2

Making a blocker against 0.96.2.... If anyone has anything to add to Rural notes, it'd be
appreciated ([~jmspaggi] Do we need to integrate your page into refguide?)

> 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.
