Mithun Radhakrishnan created HCATALOG-389:
---------------------------------------------
Summary: hcat_ping (script to check if HCatalog server is
running/reachable)
Key: HCATALOG-389
URL: https://issues.apache.org/jira/browse/HCATALOG-389
Project: HCatalog
Issue Type: New Feature
Components: client
Affects Versions: 0.4.1
Reporter: Mithun Radhakrishnan
Assignee: Mithun Radhakrishnan
Priority: Minor
Fix For: 0.5
It would be nice to have a script that checks if hcat_server is running,
whether it's reachable and if it's "healthy". The current definition of
"healthy" implies:
1. HCatalog responds to requests to list tables/databases.
2. Tables can be created/dropped in HCatalog.
3. When managed tables are used, table-directories are created/deleted on the
DFS.
4. (Future:) ActiveMQ events are being posted correctly, when tables/partitions
are created/dropped.
Monitoring apps might use this script to detect when HCatalog is down.
I'll post a trivial script that does 1-3, shortly.
