This patch leverages the AdlFileSystem in Hadoop to allow Impala to talk to the Azure Data Lake Store. This patch has functional changes as well as adds test infrastructure for testing Impala over ADLS. We do not support ACLs on ADLS since the Hadoop ADLS connector does not integrate ADLS ACLs with Hadoop users/groups. For testing, we use the azure-data-lake-store-python client from Microsoft. This client seems to have some consistency issues. For example, a drop table through Impala will delete the files in ADLS, however, listing that directory through the python client immediately after the drop, will still show the files. This behavior is unexpected since ADLS claims to be strongly consistent. Some tests have been skipped due to this limitation with the tag SkipIfADLS.slow_client. Tracked by IMPALA-5335. The azure-data-lake-store-python client also only works on CentOS 6.6 and over, so the python dependencies for Azure will not be downloaded when the TARGET_FILESYSTEM is not "adls". While running ADLS tests, the expectation will be that it runs on a machine that is at least running CentOS 6.6. Note: This is only a test limitation, not a functional one. Clusters with older OSes like CentOS 6.4 will still work with ADLS. Added another dependency to bootstrap_build.sh for the ADLS Python client. Testing: Ran core tests with and without TARGET_FILESYSTEM as 'adls' to make sure that all tests pass and that nothing breaks.

|
|
# you need to have:
|
|
#
|
|
# 1. At least 8GB of free disk space
|
|
# 4. A connection to the internet (parts of the build download dependencies)
