Hi, Did you get any solution to this ?. I am facing the same issue

@Wynner No only windows end point is there as of now. Can it be achieved using ExecuteScript Processor in groovy or any other language.??

Still struggling in converting Bytes from Hbase to proper data type, when data is fetched using GetHBase processor in Nifi @Matt Burgess @Bryan Bende @Matt Clarke Thanks in advance

nishantgupta101 · ‎04-03-2018

Thanks @Matt Burgess I am already having the flow as GetHBase -> EvaluateJsonPath -> ReplaceText -> PutDatabaseRecord Where , GetHbase is getting data from hbase tablesEvaluateJsonPath is saving value in form of attributes ReplaceText is forming data in a line ${Name}, ${age}, ${city} PutDatabaseRecord is saving data in SQL data base. Issue is where my data contains value like "@\uFFFDs\uFFFD\uFFFD\u001E\uFFFD". (it should be some integer/double value) i am not able to figure it out which processor to use.. or anyother way to proceed.

Bottleneck is I am getting the data from hbase in below format : "D:Field1":"@'\uFFFD\uFFFDQ\uFFFD\u001F" "D:Feild2":"@\uFFFDs\uFFFD\uFFFD\u001E\uFFFD" "D:Feild3":"@O\u0006fffff" "D:Feild4":"\u0000\u0000\u0000\u0000\u0000\u0000\u0000\u0000" "D:Feild5":"\u0000\u0000\u0000\u0000\u0000\u0000\u0000H" This data is in this format because I am putting data in hbase using spark job and converting it in Bytes import org.apache.hadoop.hbase.util.Bytes input._2.foreach( record => { put.addColumn(Bytes.toBytes(builder.columnFamilyName),Bytes.toBytes(record._1),record._2.get.toBytes) })

Exporting nifi template to minifi config.yml template does not copy any reference to custom.properties. Is there any way to do that ?

The issue that I was facing was in Nifi 1.3 I raised this issue with Apache team. They fixed it. https://issues.apache.org/jira/browse/MINIFI-403 Plus, you can try for Nifi 1.4 and Minifi 0.2.1, I am not facing issues now
