Paul Rogers updated DRILL-4812: ------------------------------- Labels: easyfix easytest ready-to-commit windows (was: easyfix easytest windows) Reviewer: Paul Rogers > Wildcard queries fail on Windows > -------------------------------- > > Key: DRILL-4812 > URL: https://issues.apache.org/jira/browse/DRILL-4812 > Project: Apache Drill > Issue Type: Bug > Components: Storage - Other > Affects Versions: 1.7.0 > Environment: Windows 7 > Reporter: Mike Lavender > Labels: easyfix, easytest, ready-to-commit, windows > > Wildcards within the path of a query are not handled on windows and result in > a "String index out of range" exception. > for example: > {noformat} > 0: jdbc:drill:zk=local> SELECT SUM(qty) as num FROM > dfs.parquet.`/trends/2016/1/*/*/3701`; > Error: VALIDATION ERROR: String index out of range: -1 > SQL Query null > {noformat} > ---- > The problem exists within: > exec\java-exec\src\main\java\org\apache\drill\exec\store\dfs\FileSelection.java > private static Path handleWildCard(final String root) > This function is looking for the index of the system specific PATH_SEPARATOR > which on windows is '\' (from System.getProperty("file.separator")). The > path passed in to handleWildcard will not ever have those type of path > separators as the Path constructor (from org.apache.hadoop.fs.Path) sets all > the path separators to '/'. > NOTE: > private static String removeLeadingSlash(String path) > in that same file explicitly looks for '/' and does not use the system > specific PATH_SEPARATOR. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
