             Summary: Skip the plugin if it throws errors when registering schemas
                 Key: DRILL-4613
                 URL: https://issues.apache.org/jira/browse/DRILL-4613
             Project: Apache Drill
          Issue Type: Improvement
            Reporter: Venki Korukanti
            Assignee: Venki Korukanti


Currently when registering schemas in root schema, if a plugin throws an exception we fail
the query. This causes every query to fail as every query needs a complete schema tree. Plugins
could throw exceptions due to transient errors (storage server is temporarily not reachable).


If a plugin throws an exception during schema registration, log an error, skip the plugin
and continue registering schemas from rest of the plugins. If the user is querying tables
from other plugins, the query should succeed. If the user is querying the tables in skipped
plugin, a table not found exception is thrown.
