I am attempting to run a sqoop command with a free-form query, because I need to perform an aggregation. It's being submitted via the Hue interface, as an Oozie workflow. The following is a scaled-down version of the command and query. When the command is processed, the "--query" statement (enclosed in quotes) results in each portion of the query to be interpreted as unrecognized arguments, as shown in the error following the command. In addition, the target directory is being misinterpreted. What is preventing this from running, and what can be done to resolve it? The ${env} and ${shard} variables are being properly parsed, as reflected in the last error message.
Thank you!

I was able to get this working. The solution is to submit all of the query elements as separate arguments. Nothing should be in the "Command" window. Instead, starting with "import" as the first argument, enter each part of the query as a separate argument. Properties and values for each element are entered as separate arguments. For example:
arg: import arg: --connect arg: jdbc:mysql.... arg: --username arg: [username] arg: --password-file arg: [password file] arg: --query arg: select ..... arg: --target-dir arg: [target]
The workflow performs as expected.
