----------------------------------
Summary: Unnecessary inclusion of empty string match result in Json
Key: STORM-3143
URL: https://issues.apache.org/jira/browse/STORM-3143
Project: Apache Storm
Issue Type: Bug
Components: storm-webapp
Affects Versions: 2.0.0
Reporter: Zhengdai Hu
Assignee: Zhengdai Hu
Fix For: 2.0.0
`FindNMatches()` didn't correctly filter out empty match result in
`substringSearch()` and hence send back an empty map to user. I don't know if
this the desired behavior but a fix to current behavior will make metrics for
logviewer easier to implement.
An example of current behavior:
{code:json}
{
"fileOffset": 1,
"searchString": "sdf",
"matches": [
{
"searchString": "sdf",
"fileName": "word-count-1-1530815972/6701/worker.log",
"matches": [],
"port": "6701",
"isDaemon": "no",
"startByteOffset": 0
}
]
}
{code}
Desired behavior:
{code:json}
{
"fileOffset": 1,
"searchString": "sdf",
"matches": []
}
{code}
