Python 3 moved several things around or removed deprecated functions / fields: - sys.maxint was removed, but sys.maxsize provides similar functionality - long was removed, but int provides the same range - file() was removed, but open() already provided the same functionality - Exception.message was removed, but str(exception) is equivalent - Some encodings (like hex) were moved to codecs.encode() - string.letters -> string.ascii_letters - string.lowercase -> string.ascii_lowercase - string.strip was removed This fixes all of those locations. Python 3 also has slightly different rounding behavior from round(), so this changes round() to use future's builtins.round() to get the Python 3 behavior. This fixes the following pylint warnings: - file-builtin - long-builtin - invalid-str-codec - round-builtin - deprecated-string-function - sys-max-int - exception-message-attribute Testing: - Ran cores tests Change-Id: I094cd7fd06b0d417fc875add401d18c90d7a792f Reviewed-on: http://gerrit.cloudera.org:8080/19591 Reviewed-by: Joe McDonnell <joemcdonnell@cloudera.com> Tested-by: Joe McDonnell <joemcdonnell@cloudera.com>

# Parses a base64-encoded profile provided via stdin. It accepts
|
|
# three common formats:
|
|
#
|
|
# 1. Impala profile logs of the format
|
|
# "<ts> <queryid> <base64encoded, compressed thrift profile>"
|
|
# 2. Just the base64-encoded compressed thrift profile
|
|
# 3. Base-64 encoded uncompressed thrift profile.
|
|
#
|
|
# In all cases, the script expects one profile per line.
|
|
#
|
|
# For example:
|
|
#
|
|
# $ cat logs/cluster_test/custom_cluster_tests/profiles/impala_profile_log \
|
|
# | head -n 1 | awk '{ print $3 }' | parse-profile.py
