问题 Is there any way to run impala shell with SQL script with parameters? For example: impala-shell -f /home/john/sql/load.sql /dir1/dir2/dir3/data_file I got errors: Error, could not parse arguments "-f /home/john/sql/load.sql /dir1/dir2/dir3/data_file” 回答1: No, you can specify a file of sql statements with -f , but it does not take a file of parameters. See the impala-shell documentation for more details: http://www.cloudera.com/content/cloudera/en/documentation/core/latest/topics/impala_impala

问题 I have two Hive UDFs in Java which work perfectly well in Hive. Both functions are complimentary to each other. String myUDF(BigInt) BigInt myUDFReverso(String) myUDF("myInput") gives some output which when myUDFReverso(myUDF("myInput")) should give back myInput This works in Hive but when I try to use it in Impala (version 1.2.4) it gives expected answer for myUDF(BigInt) (the answer printed is correct) but the answer when passed to myUDFReverso(String) doesn't give back original answer).

问题 EDIT: This question and answer applies to anyone who is experiencing the exception stated in the subject line: TTransportException(type=4, message='TSocket read 0 bytes') ; whether or not Cloudera and/or HappyBase is involved. The root issue (as it turned out) stems from mismatching protocol and/or transport formats on the client-side with what the server-side is implementing, and this can happen with any client/server paring. Mine just happened to be Cloudera and HappyBase, but yours needn't
