First I add the hive-serdex-1.0-snapshot jar file hive> ADD JAR /usr/lib/hive/lib/hive-serdes-1.0-SNAPSHOT.jar; Added [/usr/lib/hive/lib/hive-serdes-1.0-SNAPSHOT.jar] to class path Added resources: [/usr/lib/hive/lib/hive-serdes-1.0-SNAPSHOT.jar] And than I add the json-serde-1.3.7 jar file (I believe this is why I get the error)   hive> ADD JAR /usr/lib/hive/lib/json-serde-1.3.7-jar-with-dependencies.jar; Added [/usr/lib/hive/lib/json-serde-1.3.7-jar-with-dependencies.jar] to class path Added resources: [/usr/lib/hive/lib/json-serde-1.3.7-jar-with-dependencies.jar]   But when I try to create this table in hive: CREATE EXTERNAL TABLE tweets ( id BIGINT, created_at STRING, source STRING, favorited BOOLEAN, retweet_count INT, retweeted_status STRUCT< text:STRING, `user`:STRUCT<screen_name:STRING,name:STRING>>, entities STRUCT< urls:ARRAY<STRUCT<expanded_url:STRING>>, user_mentions:ARRAY<STRUCT<screen_name:STRING,name:STRING>>, hashtags:ARRAY<STRUCT<text:STRING>>>, text STRING, `user` STRUCT< screen_name:STRING, name:STRING, friends_count:INT, followers_count:INT, statuses_count:INT, verified:BOOLEAN, utc_offset:INT, time_zone:STRING>, in_reply_to_screen_name STRING ) ROW FORMAT SERDE 'com.cloudera.hive.SERDE.JSONSerDe' LOCATION '/user/cloudera/flume/tweets' I get this error: Error while processing statement: FAILED: Execution Error, return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask.
