----------------------------------
Summary: change "-tokenCacheFile" option to support non-local FS
URIs.
Key: HADOOP-11089
URL: https://issues.apache.org/jira/browse/HADOOP-11089
Project: Hadoop Common
Issue Type: Improvement
Components: util
Reporter: zhihai xu
Assignee: zhihai xu
change "-tokenCacheFile" option to support non-local FS URIs.
The current code in GenericOptionsParser only support local FS URIs, It will be
better to support non-local FS URIs.
{code}
FileSystem localFs = FileSystem.getLocal(conf);
Path p = localFs.makeQualified(new Path(fileName));
if (!localFs.exists(p)) {
throw new FileNotFoundException("File "+fileName+" does not exist.");
}
{code}
We can change above code to
{code}
FileSystem localFs = FileSystem.getLocal(conf);
Path p = localFs.makeQualified(new Path(fileName));
if (!p.getFileSystem(conf).exists(p)) {
throw new FileNotFoundException("File "+fileName+" does not exist.");
}
{code}
This issue will depend on MAPREDUCE-6086.
