Istvan Toth updated HBASE-28214:
--------------------------------
Description:
The README for the Spark connector details the classpath requirements for the
HBase server side, but does not talk about how to set up the Spark classpath
for HBase.
The Cloudera docs
[https://docs.cloudera.com/cdp-private-cloud-base/7.1.9/accessing-hbase/topics/hbase-configure-spark-connector.html]
suggest using "hbase mapredcp" It is, however inconsistent, as "hbase
mapredcp" includes the unshaded hadoop libraries, while the example command
line omits the hadoop libraries.
(and seem to depend on the Hadoop JARs included in the hbase-shaded-mapreduce
JAR, or perhaps on the existing Hadoop JARs on the Spark classpath, depending
on the classpath ordering and the phase of the moon).
Figure this out, and update the documentation.
