I believe this is because you have a "hadoop" directory in /usr/hdp ... /usr/hdp should only contain versions and "current". If there's another directory, it would cause the hdp-select tool to fail.

Function before: # Print the installed packages def printVersions(): result = {} for f in os.listdir(root): if f not in [".", "..", "current", "share", "lost+found"]: result[tuple(map(int, versionRegex.split(f)))] = f keys = result.keys() keys.sort() for k in keys: print result[k] Function after modification: # Print the installed packages def printVersions(): result = {} for f in os.listdir(root): if f not in [".", "..", "current", "share", "lost+found"]: try: result[tuple(map(int, versionRegex.split(f)))] = f except: pass keys = result.keys() keys.sort() for k in keys: print result[k] Hadoop cluster installation need to be automated so this workaround is not a solution. Script /usr/bin/hdp-select appears during installation and it doesn't come with any rpm package. It can be a bug in the script or maybe it fails only with some specific python versions only. Do you know the problem? If so what can be the solution? Thanks in advance, Pawel
