--------------------------------------------
Hcatalog API does not have the ability to show databases.
> HiveCatalogService has hardcode the database name "default" to check whether
> the service is up.

> Project: Falcon
> Issue Type: Bug
> Affects Versions: 0.5
> Reporter: Venkatesh Seetharam

> Don Bosco Durai reported in an email to me:
> While debugging the issue, it seems HiveCatalogService has hardcode the
> database name "default" to check whether the service is up. I think this
> check will fail if the customer has dropped the database "default" in
> production.
> {code}
> @Override
> public boolean isAlive(final String catalogUrl,
> final String metaStorePrincipal) throws
> FalconException {
> LOG.info("Checking if the service is alive for: " + catalogUrl);
> try {
> HCatClient client = getProxiedClient(catalogUrl,
> metaStorePrincipal);
> HCatDatabase database = client.getDatabase("default");
> return database != null;
> } catch (HCatException e) {
> throw new FalconException("Exception checking if the service is
> alive:" + e.getMessage(), e);
> }
> }
> {code}
> Thanks Bosco.
