Steven Phillips commented on DRILL-3867:
----------------------------------------

We should store the paths relative to the directory containing the metadata 
file.

> Metadata Caching : Moving a directory which contains a cache file causes 
> subsequent queries to fail

> The below sequence of steps reproduces the issue
> 1. Create the cache file
> {code}
> 0: jdbc:drill:zk=10.10.103.60:5181> refresh table metadata 
> dfs.`/drill/testdata/metadata_caching/lineitem`;

> | true  | Successfully updated metadata for table

> {code}
> 2. Move the directory
> {code}
> hadoop fs -mv /drill/testdata/metadata_caching/lineitem /drill/
> {code}
> 3. Now run a query on top of it
> {code}
> 0: jdbc:drill:zk=10.10.103.60:5181> select * from dfs.`/drill/lineitem` limit 
> 1;
> Error: SYSTEM ERROR: FileNotFoundException: Requested file 
> maprfs:///drill/testdata/metadata_caching/lineitem/2006/1 does not exist.
> [Error Id: b456d912-57a0-4690-a44b-140d4964903e on pssc-66.qa.lab:31010] 
> (state=,code=0)
> {code}
> This is obvious given the fact that we are storing absolute file paths in the 
> cache file
