Subject [jira] [Created] (DRILL-1805) view not found if view file directory contains child with colon in simple name
Date Wed, 03 Dec 2014 20:33:12 GMT
Daniel Barclay (Drill/MapR) created DRILL-1805:
--------------------------------------------------

             Summary: view not found if view file directory contains child with colon in simple
name
                 Key: DRILL-1805
                 URL: https://issues.apache.org/jira/browse/DRILL-1805
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Daniel Barclay (Drill/MapR)


Scanning the file system for view files fails (resulting in "Table 'vv' not found" errors)
if the directory being scanned for view files contains a file whose simple name (last pathname
segment) contains a colon.

For example, the unit test method testDRILL_811View in Drill's ./exec/java-exec/src/test/java/org/apache/drill/TestExampleQueries.java
fails if /tmp contains a file named like "aptitude-root.1528:JIsVaZ".

The cause is that Hadoop filesystem glob-pattern-matching code (org.apache.hadoop.fs.Globber's
glob() and org.apache.hadoop.fs.Path's Path(Path,String)) mixes up relative file pathname
strings and relative URI-style Path strings.

Action items:
1) Report Hadoop bug to Hadoop.
2) Review Drill's handling and propagation of the error.
