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`;
+-------+-------------------------------------------------------------------------------------+
|  ok   |                                       summary                                       |
+-------+-------------------------------------------------------------------------------------+
| true  | Successfully updated metadata for table /drill/testdata/metadata_caching/lineitem.  |
+-------+-------------------------------------------------------------------------------------+
1 row selected (1.558 seconds)
{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
