commit 27e207b02c28d5ac23835a96a0823078def14a8b Author: Alexey Serbin <[email protected]> AuthorDate: Thu Oct 24 10:01:27 2019 -0700 [scripts] a tool to print out HybridTime timestamps This is Todd's script to output HybridTime timestamps in human-readable form (works with Python2 and Python3). The script reads from standard input until EOF/EOS and outputs the result into standard output. The script is useful when analyzing hybrid timestamps found in Kudu WAL files. For example: $ echo 6435399373400084500 | python convert-hybrid-timestamp.py 2019-10-15 05:27:05.146505 L=20 Change-Id: Ifc5b0d20c6f1bca0994d00a347ff14e4ae64a14c Reviewed-on: http://gerrit.cloudera.org:8080/14541 Tested-by: Alexey Serbin <[email protected]> Reviewed-by: Bankim Bhavsar <[email protected]> Reviewed-by: Andrew Wong <[email protected]> --- src/kudu/scripts/convert-hybrid-timestamp.py | 40 ++++++++++++++++++++++++++++ 1 file changed, 40 insertions(+) diff --git a/src/kudu/scripts/convert-hybrid-timestamp.py b/src/kudu/scripts/convert-hybrid-timestamp.py new file mode 100644 index 0000000..2ee09d3 --- /dev/null +++ b/src/kudu/scripts/convert-hybrid-timestamp.py @@ -0,0 +1,40 @@ +#!/usr/bin/env python +# +# Licensed to the Apache Software Foundation (ASF) under one +# or more contributor license agreements.
