I would like us to consider bumping version of Sqoop in Bigtop trunk (and Bigtop 0.6) from 1.99.1 to 1.99.2. Here's why:
As a part of
BIGTOP-949, I started playing around with Sqoop in Bigtop trunk. During this process, I found out that even simple commands like show connector --all fail with an error like:
Exception has occurred during processing command
Exception: com.sun.jersey.api.client.UniformInterfaceException Message: GET http:
It turns out that Sqoop's tomcat is trying to bind to port 8080 but MR2 uses the same port 8080 for its shuffle manager (via a property called mapreduce.shuffle.port), hence the error.
This makes Sqoop unusable on Bigtop trunk and there not much point in writing integration tests for it. The upstream Sqoop JIRA (
SQOOP-881) resolves this issue and changes the default Tomcat port to 12000. However, the first release of Sqoop that contains this fix is 1.99.2. Morever, 1.99.2 contains other many other improvements related to Sqoop2.
Given the usability of current Sqoop version in trunk, I would suggest we bump up the sqoop version from 1.99.1 to 1.99.2 for Bigtop 0.6. Sorry for the late timing of this request. I would love to hear your thoughts or concerns here, so please share!
