Description

MergeRecord ignores "Max Bin Age" property and does not merge records at all.

Only NiFi 1.8.0 is affected.  

The attached test case should generate 2 types of CSV files:

column1;column2
A1;B1
A1;B1
A1;B1
A1;B1
A1;B1
A1;B1
A1;B1
A1;B1
A1;B1
A1;B1
A1;B1
A1;B1
A1;B1
...and so on for many rows...

 and

column1;column2
A2;B2
A2;B2
A2;B2
A2;B2
A2;B2
A2;B2
A2;B2
A2;B2
A2;B2
...and so on for many rows...

It works as expected for NiFi 1.6.0 and 1.7.1.

But using NiFi 1.8.0 I only get hundreds of files with just 1 record like the following:

column1;column2
A1;B1

 and

column1;column2
A2;B2
