--------------------------------------
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.
