Enis Soztutar commented on HBASE-6824:
--------------------------------------
I would like to get this in 0.94 as well. It does change the location of where
coprocessor jars are saved though. Not sure whether this breaks BC. Any
comments [~lhofhansl]?
> Introduce ${hbase.local.dir} and save coprocessor jars there

> Project: HBase

> 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.
