- making the coordinator asynchronous
- renamed ImpalaBackendService to ImpalaInternalService;
- new class ImpalaServer implements ImpalaService and ImpalaInternalService
- renaming ImpalaInternalService fields to conform to c++ style
- merged impala-service.{cc,h} and backend-service.{cc,h} into impala-server.{cc,h}
- added TStatusCode field to Status.ErrorDetail
- removed ImpalaInternalService.CloseChannel
Also removed JdbcDriverTest.java
(CDH/hive-odbc-test) passes (except those with "create table" and "show table".
We should have nightly regression of the odbc test to run against impalad.
There're still a few issues:
1. running with num_node > 0 crashes the coordinator;
2. work around for a few ODBC jiras
3. no test for bool/timestamp because ODBC doesn't support them.
review: issue 110
At the same time, this patch removes the partitionKeyRegex in favour
of explicitly sending a list of literal expressions for each file path
from the front end.
- added option to run with derby metastore, based on whether env var METASTORE_IS_DERBY is set
- emoved hardwired file locations from planner tests
- switching to linking statically against libthrift.a
Also added script rebuild.sh, which contains the build steps of buildall.sh (against impala sources).
- DataStreamSender: sender side (1:n) for a single stream
- DataStreamMgr: receiver side; singleton class for all incoming streams active at a node
Changed ExecNode::GetNext() to return eos indicator explicitly; this allows us to pass incoming TRowBatches (which may not be full) up w/o copying the data.
Added data-stream-test.
