Hive

问题 I am trying to query a hive table using spark in Java. My hive tables are in an EMR cluster 5.12. Spark version is 2.2.1 and Hive 2.3.2. When I ssh into the machine and I connect to the spark-shell I am able to query the hive tables with no issues. But when I try to query using a custom jar then I get the following exception: java.lang.IllegalArgumentException: Error while instantiating 'org.apache.spark.sql.hive.HiveSessionStateBuilder': at org.apache.spark.sql.SparkSession$.org$apache$spark

问题 I am trying to delete a part of a string in HIVE. I want to delete the last eleven characters for all records in a column. The data looks like: 1018492743|0001-01-01 I want it to look like: 1018492743 The code I have tried looks like: Select right(a.ord_id, len(a.ord_id)-ll) It isn't working because len isnt a function in HIVE Another issue I have is that some of the records are already in the correct format. Does this mean I need to create a case statement that checks for this? 回答1: You can

问题 I want to create a HIVE table that will read in semicolon separated values, but my code keeps giving me errors. Does anyone have any suggestions?
