> Currently mergeBinaryTokens() is called by every invocation of obtainTokensForNamenodesInternal(FileSystem,
Credentials, Configuration) in the loop of obtainTokensForNamenodesInternal(Credentials, Path[],
Configuration).
> This can be simplified so that mergeBinaryTokens() is called only once in obtainTokensForNamenodesInternal(Credentials,
Path[], Configuration).
