Steps tried to reproduce this issue,
1. Download sdk from cask.co/Downloads
2. Start CDAP
3. Go to market and add "Organization Data from Crunchbase" datapack
Step 3 should create a stream named "organizations" and for some reason it was not explorable. The way UI determines if a dataset/stream is explorable or not is by,
1. Checking dataset/stream spec for "explore.database.name" or "explore.table.name"
2. Checking /explore/tables end point for "stream_<streamName>" or "dataset_<datasetName>"
In this case UI got "organizations" in neither calls. However it had "explore" SystemTags and there is data ingested in it. User was able "view events" from UI but not explore them
