> "is not match table meta grammar error" with sentry-1.7
> --------------------------------------------------------
>
> Key: SENTRY-2439
> URL: https://issues.apache.org/jira/browse/SENTRY-2439
> Project: Sentry
> Issue Type: Bug
> Components: Sentry
> Affects Versions: 1.7.0
> Reporter: Shishr Prakash
> Priority: Major
>
> [What happened]
> After enabling sentry I am getting below error with DDLs like DROP table .
> similar to sentry bug-1845.
> [1] https://issues.apache.org/jira/browse/SENTRY-1845
> ====Error ===
> 2 rows selected (0.171 seconds)
> 0: jdbc:hive2://maprtest03:10000> DROP TABLE project_dev_out_hive;
> Error: Error while compiling statement: FAILED: HiveAuthzPluginException
> class
> org.apache.hadoop.hive.ql.security.authorization.plugin.HiveAuthzPluginException:
> this command DROP TABLE project_dev_out_hive is not match table meta grammar
> (state=42000,code=40000)
> ======
> It is not the same issue, but a similar issue for DROP TABLE command. The
> Sentry regex pattern for DROP TABLE command does not seem to be supporting
> backtick.
> String DROP_TABLE_REGEX = "^DROP\s+" + "TABLE\s+" + "(IF\s+EXISTS\s+)?" +
> "([A-Za-z0-9._]+)";
> Looks like it is not fixed in the latest version as well (the same pattern is
> used in the master branch as well). Hive seems to be supporting this syntax.
> ## Steps to Reproduce
> Try dropping hive table with backticks as below
> DROP TABLE `project_dev_out_hive`;
> ### What you expected to happen
> Sentry should understand backticks and it should work for every command.
