IMPALA-6341, IMPALA-5917: Reduce mem-limit for start-impala-cluster.
We've observed empirically that giving Impala 80% of system memory
doesn't leave enough room for the minicluster and ASAN overhead, leading
to the OOM killer striking during test runs (sometimes). This commit
reduces the threshol

IMPALA-6405: Error when string to decimal cast overflows
Before this patch, when there was an error when converting a string to
a decimal, a NULL was returned. In this patch, we change this behavior
so that an error is
IMPALA-6576: Add metrics for data stream service memory usage
This change adds metrics for the data stream service memory usage. Both
current and peak usage are exposed.
It adds a test to test_krpc_metrics.py to make sure that the expected
metrics are present and that the peak usage shows a non-z
IMPALA-3040: add logging to test_caching_ddl
We don't currently have enough information to reconstruct why the test
failed, so lets add logging with timestamps to understand which timeout
we're actually hitting.

IMPALA-6638: Reduce file handle cache lock contention
FileHandleCache::OpenFileHandle() currently holds the
lock while opening a file handle. This lengthens the

IMPALA-6609: Fix ownership of class members in KrpcDataStreamRecvr
A KrpcDataStreamRecvr is co-owned by the singleton KrpcDataStreamMgr
and an exchange node. It's possible that some threads (e.g. RPC service
threads) may still retain reference to the KrpcDataStreamRecvr after its
owning exchange n
IMPALA-5315: Cast to timestamp fails for -M-D format
This change allows casting of a string in 'lazy' date/time
format to timestamp. The supported lazy date formats are:
-[M]M-[d]d
-[M]M-[d]d [H]H:[m]m:[s]s[.S]
[H]H:[m]m:[s]s[.S]

FileHandleCache::OpenFileHandle() currently holds the
lock while opening a file handle. This lengthens the
duration holding the lock considerably, causing
