[ZEPPELIN-1488] JDBC Interpreter throws error while the interpreter is
downloading dependencies
### What is this PR for?
For first time, when we add dependencies for JDBC interpreter, dependencies
will start getting downloaded in background. During that time, if user runs a
paragraph of JDBC interpreter now user getting error , But instead paragraph
execution should be put on 'PENDING' state and wait for dependencies to get
downloaded and then run the paragraph
### What type of PR is it?
Bug Fix
### Todos
### What is the Jira issue?
[ZEPPELIN-1488] https://issues.apache.org/jira/browse/ZEPPELIN-1488
### How should this be tested?
prerequisites:
1. Any DB setup.(For my testing, i considered hive)
Steps:
1. Delete the local-repo folder under zeppelin project, if it exists
2. Go to interpreter settings page, provide hive connection details under
JDBC interprepreter
3. For hive interpreter to run, it needs some dependencies to be added in
interpreter settings page
For hive below dependencies needs to added
1. org.apache.hive:hive-jdbc:0.14.0
2. org.apache.hadoop:hadoop-common:2.6.0
4. Once the settings for JDBC interpreter is saved, dependencies will start
getting downloaded in background.
5. Run any paragraph with JDBC as interpreter, paragraph should not throw
error, status of the paragraph should change to 'pending' while the
dependencies are getting downloaded in background.
6. Once the downloading of dependencies is done, the paragraph which were
in pending will start executing in order depending on the execution mode of the
interpreter (i.e Shared, Scoped, Isolated)
### Screenshots (if appropriate)
### Questions:
* Does the licenses files need update? No
* Is there breaking changes for older versions? No
* Does this needs documentation? No
