[IMPALA-11165] ParseQueryOptions() cannot parse the value of some query options

• Type: Bug
• Status: Open
• Priority: Minor
• Resolution: Unresolved
• Affects Version/s: Impala 4.1.0
• Component/s: Backend
• Epic Color: ghx-label-10
• Assignee: Fang-Yu Rao

Description

We found that ParseQueryOptions() could not parse the value of some query options, e.g., 'ENABLED_RUNTIME_FILTER_TYPES', which has been extended to a set in IMPALA-10898, if the value contains commas, e.g., "BLOOM,MIN_MAX".

This issue could also be reproduced if we use Impala shell to connect to the Impala server via the beeswax protocol.
