> I have encountered a variety of Java errors while trying to get Apache
> Phoenix working with Spark. In particular, I encounter these errors when
> submitting Python jobs to the spark-shell, or running interactively in the
> scala Spark shell.
> ------- Issue 1 -------
> The first issue I encountered was that Phoenix would not work with the binary
> Spark release that includes Hadoop 2.6 (spark-1.5.2-bin-hadoop2.6.tgz). I
> tried adding the phoenix-4.6.0-HBase-1.1-client.jar to both spark-env.sh and
> spark-defaults.conf, but encountered the same error when launching
> spark-shell:
> 15/12/08 18:38:05 WARN ObjectStore: Version information not found in
> metastore. hive.metastore.schema.verification is not enabled so recording the
> schema version 1.2.0
> 15/12/08 18:38:05 WARN ObjectStore: Failed to get database default, returning
> NoSuchObjectException
> 15/12/08 18:38:05 WARN Hive: Failed to access metastore. This class should
> not accessed in runtime.
> org.apache.hadoop.hive.ql.metadata.HiveException: java.lang.RuntimeException:
> Unable to instantiate
> org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient
> at
> org.apache.hadoop.hive.ql.metadata.Hive.getAllDatabases(Hive.java:1236)
> ----- Issue 2 -----
> Alright, having given up on getting Phoenix to work with the Spark package
> that includes Hadoop, I decided to download hadoop-2.6.2.tar.gz and
> spark-1.5.2-bin-without-hadoop.tgz. I installed these, and again added
> phoenix-4.6.0-HBase-1.1-client.jar to spark-defaults.conf. In addition, I
> added the following lines to spark-env.sh:
> SPARK_DIST_CLASSPATH=$(/usr/local/hadoop/bin/hadoop classpath)
> export
> SPARK_DIST_CLASSPATH="$SPARK_DIST_CLASSPATH:/usr/local/hadoop/share/hadoop/tools/lib/*"
>
> export HADOOP_CONF_DIR=/usr/local/hadoop/etc/hadoop
> This solved "Issue 1" described above, and now spark-shell launches without
> generating an error. Nevertheless, other Spark functionality is now broken:
> 15/12/09 13:55:46 INFO repl.SparkILoop: Created spark context..
> Spark context available as sc.
> 15/12/09 13:55:46 INFO repl.SparkILoop: Created sql context..
> SQL context available as sqlContext.
> scala> val textFile = sc.textFile("README.md")
> java.lang.NoSuchMethodError:
> com.fasterxml.jackson.module.scala.deser.BigDecimalDeserializer$.handledType()Ljava/lang/Class;
> at
> com.fasterxml.jackson.module.scala.deser.NumberDeserializers$.<init>(ScalaNumberDeserializersModule.scala:49)
> at
> com.fasterxml.jackson.module.scala.deser.NumberDeserializers$.<clinit>(ScalaNumberDeserializersModule.scala)
> Note, this error goes away if I omit phoenix-4.6.0-HBase-1.1-client.jar (but
> then I have no Phoenix support, obviously). This makes me believe that
> phoenix-4.6.0-HBase-1.1-client.jar contains some conflicting version of
> Jackson FastXML classes, which are overriding Spark's Jackson classes with an
> earlier version that doesn't include this particular method. In other words,
> Spark needs one version of Jackson JARs, but Phoenix is including another
> that breaks Spark. Does this make any sense?
> Sincerely,
> Jonathan
