-----------------------------
Summary: TestByteRangeInputStream.testPropagatedClose fails and
throw NPE on branch-2
Key: HDFS-7049
URL: https://issues.apache.org/jira/browse/HDFS-7049
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Juan Yu
Priority: Minor
On branch-2, TestByteRangeInputStream.testPropagatedClose throw NPE when
HftpFileSystem$RangeHeaderUrlOpener.connect
This is due to fix of HDFS-6143 "WebHdfsFileSystem open should throw
FileNotFoundException for non-existing paths"
public ByteRangeInputStream(URLOpener o, URLOpener r) throws IOException {
this.originalURL = o;
this.resolvedURL = r;
getInputStream();
}
the getInputStream() will be called in constructor now to verify if file exists.
Since we just try to test if ByteRangeInputStream#close is called at proper
time, we could mock(ByteRangeInputStream.class, CALLS_REAL_METHODS) for testing
to avoid the NPE issue.
I believe the trunk version already does this, we just need to merge the test
from trunk.
