Let me know why the pyarrow test is failing. For one of the config "trex", I had to load an initial datafile for a dictionary which is used to augment the rest of the datasets. In the dummy data, the dictionary file was truncated so I had to fudge that. I'm not sure if that is the issue.
 @ontocord it just needs a rerun and it will be good to go. THanks @tanmoyio. How do I do a rerun? @ontocord contributor can’t rerun it, the maintainers will rerun it, it may take lil bit of time as there are so many PRs left to be reviewed and merged  @lhoestq not sure why it is failing. i've made all modifications.  merging since the CI is fixed on master
