[ZEPPELIN-2124] Missing dependencies array in interpreter.json after upgrade from 0.6.2 to 0.7.0
### What is this PR for? If there is no `dependencies` field specified in `interpreter.json`, front-end throws error because it tries to push new element to undefined variable. This PR fixes this issue by setting initial value of `dependencies` to empty array. ### What type of PR is it? Bug Fix ### What is the Jira issue? [ZEPPELIN-2124](https://issues.apache.org/jira/browse/ZEPPELIN-2124) ### How should this be tested? Remove `dependencies` field from `conf/interpreter.json` and try to add new dependencies in http://localhost:8080/#/interpreter page. ### Questions: * Does the licenses files need update? no * Is there breaking changes for older versions? no * Does this needs documentation? no Author: Mina Lee <mina...@apache.org> Closes #2142 from minahlee/ZEPPELIN-2124 and squashes the following commits: 01b27eb [Mina Lee] Assign init value for dependencies field (cherry picked from commit f9a8a6f6e8e9959b5bed0a69723b934a25b7f261) Signed-off-by: Jongyoul Lee <jongy...@apache.org> Project: http://git-wip-us.apache.org/repos/asf/zeppelin/repo Commit: http://git-wip-us.apache.org/repos/asf/zeppelin/commit/56fa8b53 Tree: http://git-wip-us.apache.org/repos/asf/zeppelin/tree/56fa8b53 Diff: http://git-wip-us.apache.org/repos/asf/zeppelin/diff/56fa8b53 Branch: refs/heads/branch-0.7 Commit: 56fa8b5349fa6889fa4d5097497bef7282a7c647 Parents: adf2b12 Author: Mina Lee <mina...@apache.org> Authored: Thu Mar 16 10:57:38 2017 +0900 Committer: Jongyoul Lee <jongy...@apache.org> Committed: Fri Mar 17 00:00:37 2017 +0900 ---------------------------------------------------------------------- .../java/org/apache/zeppelin/interpreter/InterpreterSetting.java | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) ---------------------------------------------------------------------- http://git-wip-us.apache.org/repos/asf/zeppelin/blob/56fa8b53/zeppelin-zengine/src/main/java/org/apache/zeppelin/interpreter/InterpreterSetting.java ---------------------------------------------------------------------- diff --git a/zeppelin-zengine/src/main/java/org/apache/zeppelin/interpreter/InterpreterSetting.java b/zeppelin-zengine/src/main/java/org/apache/zeppelin/interpreter/InterpreterSetting.java index 57c6acc..30a4967 100644 --- a/zeppelin-zengine/src/main/java/org/apache/zeppelin/interpreter/InterpreterSetting.java +++ b/zeppelin-zengine/src/main/java/org/apache/zeppelin/interpreter/InterpreterSetting.java @@ -65,7 +65,7 @@ public class InterpreterSetting { @SerializedName("interpreterGroup") private List<InterpreterInfo> interpreterInfos; private final transient Map<String, InterpreterGroup> interpreterGroupRef = new HashMap<>(); - private List<Dependency> dependencies; + private List<Dependency> dependencies = new LinkedList<>(); private InterpreterOption option; private transient String path;
