Subject Re: Re: error when get data from Phoenix 4.5.2 on CDH 5.5.x by spark 1.5
Date Fri, 08 Jan 2016 15:23:11 GMT
[Sent this same message from another account, apologies if anyone gets a
double-post]

Thanks for the update. I hadn’t even seen the ‘SPARK_DIST_CLASSPATH’
setting until just now, but I suspect for CDH that might be the only way to
do it.

The reason for the class path errors you see is that the ‘client’ JAR on
its own ships a few extra dependencies (i.e. com.fasterxml.jackson) which
are incompatible with newer versions of Spark. The ‘client-spark’ JAR
attempts to remove those dependencies which would conflict with Spark,
although a more elegant solution will likely come with PHOENIX-2535 (
https://issues.apache.org/jira/browse/PHOENIX-2535)

Re: speed, the spark integration should be just about as fast as the
MapReduce and Pig integration. At the 3T level, your likely bottleneck is
disk IO just to load the data in, although network IO is also a possibility
here as well. Assuming you have a sufficient number of Spark workers with
enough RAM allocated, once the data is loaded into Spark initially,
operations on that dataset should proceed much faster, as much of the data
will be available in RAM vs disk.

Best of luck,

Josh
