[jira] [Work logged] (BEAM-13760) Add randomness to default Dataflow job name in Python sdk
[ https://issues.apache.org/jira/browse/BEAM-13760?focusedWorklogId=717090&page=com.atlassian.jira.plugin.system.issuetabpanels:worklog-tabpanel#worklog-717090 ]

Work Description: thorbjorn444 opened a new pull request #16641:
URL: https://github.com/apache/beam/pull/16641
Currently, the dataflow runner creates collisions if two jobs are created at the same microsecond.
This change adds eight random alphanumeric characters to the end of the job name, which increases the number of simultaneously started jobs required for collision odds to be over 50% from 2 (as they would definitely collide now) to 2 million.
This change also updates the unit test to account for the new name format.

> ---------------------------------------------------------
>
> Key: BEAM-13760
> URL: https://issues.apache.org/jira/browse/BEAM-13760
> Project: Beam
> Issue Type: Improvement
> Components: runner-dataflow
> Reporter: Will Nicholson
> Priority: P2
> Original Estimate: 48h
> Time Spent: 10m
> Remaining Estimate: 47h 50m
>
> Currently, when a Dataflow job is created with the default name in python, the name is a concatenation of the word "beamapp", the username, and the time in microseconds, as seen [here|https://github.com/apache/beam/blob/master/sdks/python/apache_beam/runners/dataflow/internal/apiclient.py#L415-L428].
> Therefore, when two jobs are created by the same user at the same time, the jobs names collide and the second job fails.
> However, the Java SDK has already solved this problem, by appending a random hex string to the job name, seen [here|https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/options/PipelineOptions.java#L338-L351].
> The objective of this issue is to align the python sdk with the java sdk, by appending a random string to the default job name.
