Description

After executing ~20-30 queries with the JDBC driver, the data returned from a "Show files" query is incorrect, particularly the isFile and isDirectory columns. The first item in the schema/directory will be correct, but subsequent items will report "false" for isFile and isDirectory.

This was tested with just a simple program that just loops through executeQuery and prints out the values for isFile and isDirectory. The JDBC driver used was the Drill 0.7 snapshot.

isFile: true
isDirectory: false
isFile: false
isDirectory: false
isFile: false
isDirectory: false
isFile: false
isDirectory: false
isFile: false
isDirectory: false
