Chen Feng created PHOENIX-6448:
----------------------------------
Summary: ConnectionQueryServicesImpl init failure may cause Full
GC.
Key: PHOENIX-6448
URL: https://issues.apache.org/jira/browse/PHOENIX-6448
Project: Phoenix
Issue Type: Bug
Reporter: Chen Feng
in ConnectionQueryServicesImpl.init()
In some cases(e.g. the user has not permissions to create SYSTEM.CATALOG),
there's only LOGGER.WARN and return null directly.
{code:java}
// Some comments here
if (inspectIfAnyExceptionInChain(e, Collections
.<Class<? extends Exception>>
singletonList(AccessDeniedException.class))) {
// Pass
LOGGER.warn("Could not check for Phoenix SYSTEM tables," +
" assuming they exist and are properly
configured");
checkClientServerCompatibility(SchemaUtil.getPhysicalName(SYSTEM_CATALOG_NAME_BYTES,
getProps()).getName());
success = true;
}
...
return null{code}
Therefore, the following scheduleRenewLeaseTasks will be skipped and no
exception is thrown.
1. scheduleRenewLeaseTasks not called
2. no renew task started
3. query will call PhoenixConection.addIteratorForLeaseRenewal() as usual
4. the scannerQueue is unlimited therefore it will always adding new items.
5. Full GC.
