Ted Yu created HBASE-8699:
-----------------------------

             Summary: Parameter to DistributedFileSystem#isFileClosed should be of type Path
                 Key: HBASE-8699
                 URL: https://issues.apache.org/jira/browse/HBASE-8699
             Project: HBase
          Issue Type: Bug
            Reporter: Ted Yu
            Assignee: Ted Yu


Here is current code of FSHDFSUtils#isFileClosed():
{code}
  boolean isFileClosed(final DistributedFileSystem dfs, final Path p) {
    try {
      Method m = dfs.getClass().getMethod("isFileClosed", new Class<?>[] {String.class});
      return (Boolean) m.invoke(dfs, p.toString());
{code}
We look for isFileClosed method with parameter type of String.

However, from hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/DistributedFileSystem.java (branch-2):
{code}
  public boolean isFileClosed(Path src) throws IOException {
{code}
The parameter type is of Path.
This means we would get NoSuchMethodException.
