Hello @priyanshu_soni    You can skip the "Timestamp" part as the same is inserted by HBase implicitly. I tried the same Query as you, excluding the Timestamp & the same was Successful:   hbase(main):018:0> put 'Table_X1','125','Cf1:CheckItem','{"ID" : "1334134","Name" : "Apparel Fabric","Path" : "Arts, Crafts & Sewing/Fabric/Apparel Fabric"}' Took 0.0077 seconds hbase(main):019:0> scan 'Table_X1' ROW COLUMN+CELL 125 column=Cf1:CheckItem, timestamp=1621593487680, value={"ID" : "1334134","Name" : "Apparel Fabric","Path" : "Arts, Crafts & Sewing/Fabric/Apparel Fabric"} 1 row(s) Took 0.0057 seconds As you may see above, the "timestamp" field corresponds to the Epoch Timestamp of the Inserted Row Time of Operation. If you wish to explicitly specify the Timestamp, You can include a EpochTime as shared below: hbase(main):020:0> put 'Table_X1','126','Cf1:CheckItem','{"ID" : "1334134","Name" : "Apparel Fabric","Path" : "Arts, Crafts & Sewing/Fabric/Apparel Fabric"}',1621593487680 Took 0.0202 seconds hbase(main):021:0> scan 'Table_X1' ROW COLUMN+CELL 125 column=Cf1:CheckItem, timestamp=1621593487680, value={"ID" : "1334134","Name" : "Apparel Fabric","Path" : "Arts, Crafts & Sewing/Fabric/Apparel Fabric"} 126 column=Cf1:CheckItem, timestamp=1621593487680, value={"ID" : "1334134","Name" : "Apparel Fabric","Path" : "Arts, Crafts & Sewing/Fabric/Apparel Fabric"} 2 row(s) Took 0.0071 seconds   Let us know if you have any issues with the Put Operation.   - Smarak ...

@umang s Based on your flow design above, it looks like you are trying to route FlowFiles by comparing attribute between two different FlowFiles? That will not work. NiFi is looking for both ${temp_array} and ${category} to exist on same flowfile being evaluated by the RouteOnAttribute processor. ... View more

@umang s if you are having url as attribute to the flowfile then you can use update attribute processor with replaceFirst function to replace 5 characters with empty string. Example:- I'm having url attribute to the flowfile with value as https://community.hortonworks.com/questions/182384/how-to-remove-just-only-5-characters-from-url.html?childToView=183771#answer-183771 Now i'm using update attribute processor and added new property in update attribute processor url ${url:replaceFirst('\w{5}', '')} (or) ${url:replaceAll('^.{0,5}', '')} Output Flowfile Attribute value:- Now we have removed first 5 characters in url attribute value by using update attribute processor. ...
