### What type of PR is it?
[Bug Fix]
### Todos
### What is the Jira issue?
* [ZEPPELIN-1725](https://issues.apache.org/jira/browse/ZEPPELIN-1725)
### How should this be tested?
Configure following as dependencies in JDBC
```
org.apache.hive:hive-jdbc:2.0.1
org.apache.hadoop:hadoop-common:2.7.1
org.apache.hive.shims:hive-shims-0.23:2.1.0
org.apache.phoenix:phoenix-core:4.7.0-HBase-1.1
```
now try changing one of it, say "org.apache.hadoop:hadoop-common:2.7.1" to
"org.apache.hadoop:hadoop-common:2.6.0"
Save should happen all the time.
### Screenshots (if appropriate)

do a check for FileNotFoundException, which would mean it was already
deleted/not present.
