zhihai xu updated YARN-3263:
Description:
ContainerManagerImpl#parseCredentials don't rewind the ByteBuffer after
credentials.readTokenStorageStream. So the next time if we access Tokens, we
will have EOFException.
The following is the code for parseCredentials in ContainerManagerImpl.
{code}
private Credentials parseCredentials(ContainerLaunchContext launchContext)
throws IOException {
Credentials credentials = new Credentials();
// Parse credentials
ByteBuffer tokens = launchContext.getTokens();
if (tokens != null) {
DataInputByteBuffer buf = new DataInputByteBuffer();
tokens.rewind();
buf.reset(tokens);
credentials.readTokenStorageStream(buf);
if (LOG.isDebugEnabled()) {
for (Token tk : credentials.getAllTokens()) {
LOG.debug(tk.getService() + " = " + tk.toString());
}
}
}
// End of parsing credentials
return credentials;
}
{code}
