Bruce Robbins updated SPARK-22940:
----------------------------------
Description:
On platforms that don't have wget installed (e.g., Mac OS X), test suite
org.apache.spark.sql.hive.HiveExternalCatalogVersionsSuite throws an exception
and aborts:
java.io.IOException: Cannot run program "wget": error=2, No such file or
directory
HiveExternalCatalogVersionsSuite uses wget to download older versions of Spark
for compatibility testing. First it uses wget to find a suitable mirror, and
then it uses wget to download a tar file from the mirror.
There are several ways to fix this (in reverse order of difficulty of
implementation)
1. Require Mac OS X users to install wget if they wish to run unit tests (or at
the very least if they wish to run HiveExternalCatalogVersionsSuite). Also,
update documentation to make this requirement explicit.
2. Fall back on curl when wget is not available.
3. Use an HTTP library to query for a suitable mirror and download the tar file.
Number 2 is easy to implement, and I did so to get the unit test to run. But
relies on another external program.
Number 3 is probably slightly more complex to implement and requires more
corner-case checking (e.g, redirects, etc.).
