---------------------------------

       Resolution: Fixed
    Fix Version/s: 0.96.0
     Release Note: Added a configuration "hbase.local.dir" which defaults to ${hbase.tmp.dir}/local/. Coprocessor jars, and other local data for region servers are written to this location. 
     Hadoop Flags: Reviewed
           Status: Resolved  (was: Patch Available)

Committed v3 to trunk. Thanks for review Andrew.

> We need to make the temp directory where coprocessor jars are saved configurable. For this we will add hbase.local.dir configuration parameter. 
> Windows tests are failing due to the pathing problems for coprocessor jars:
> Two HBase TestClassLoading unit tests failed due to a failiure in loading the test file from HDFS:
> {code}
> testClassLoadingFromHDFS(org.apache.hadoop.hbase.coprocessor.TestClassLoading): Class TestCP1 was missing on a region
> testClassLoadingFromLibDirInJar(org.apache.hadoop.hbase.coprocessor.TestClassLoading): Class TestCP1 was missing on a region
> {code}
> The problem is that CoprocessorHost.load() copies the jar file locally, and schedules the local file to be deleted on exit, but calling FileSystem.deleteOnExit(). However, the filesystem is not the file system of the local file, it is the distributed file system, so on windows, the Path fails.
