> get local file system fails with a casting error
> ------------------------------------------------
>
> Key: HADOOP-18904
> URL: https://issues.apache.org/jira/browse/HADOOP-18904
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: ConfX
> Priority: Major
> Labels: pull-request-available
>
> h2. What happened
> After setting {{{}fs.file.impl=org.apache.hadoop.fs.RawLocalFileSystem{}}},
> trying to acquire local file system using the {{getLocal}} in
> {{org.apache.hadoop.fs}} fails with {{java.lang.ClassCastException}}
> h2. Where's the bug
> In the function {{getLocal}} of {{FileSystem}} in HCommon:
> {code:java}
> public static LocalFileSystem getLocal(Configuration conf)
> throws IOException {
> return (LocalFileSystem)get(LocalFileSystem.NAME, conf);
> } {code}
> the returned file system is directly cast to LocalFileSystem without
> checking. If the user set the implementation of the local filesystem to be
> Raw rather than Checksum, this type cast would fail.
> h2. How to reproduce
> # Set {{fs.file.impl=org.apache.hadoop.fs.RawLocalFileSystem}}
> # Run the following test in HBase:
> {{org.apache.hadoop.hbase.TestHBaseTestingUtility#testMiniDFSCluster}}
> and the following exception should be observed:
> {code:java}
> java.lang.ClassCastException: class org.apache.hadoop.fs.RawLocalFileSystem
> cannot be cast to class org.apache.hadoop.fs.LocalFileSystem
> (org.apache.hadoop.fs.RawLocalFileSystem and
> org.apache.hadoop.fs.LocalFileSystem are in unnamed module of loader 'app')
> at org.apache.hadoop.fs.FileSystem.getLocal(FileSystem.java:441)
> at
> org.apache.hadoop.hbase.HBaseTestingUtility.getNewDataTestDirOnTestFS(HBaseTestingUtility.java:550)
> ...{code}
> Or simply set the configuration parameter and call the method using a
> {{Configuration}} object and the exception would be triggered.
