   <CausedBy> com.tibco.bw.palette.hadoop.runtime.exception.HadoopException: Error Occurred: java.lang.IndexOutOfBoundsException: start 0, end 8192, s.length() 8191
                at java.lang.AbstractStringBuilder.append(AbstractStringBuilder.java:512)

Environment

Resolution

The error can be resolved by forcing the character encoding of the Java runtime environment as ISO-8859-1. For this we can make changes at the following path. 

Run-->Debug Configuration-->Arguments-->VM Arguments: We appended "-Dfile.encoding= ISO-8859-1" at the end of the existing value.

An alternate way is to insert the property "-Dfile.encoding= ISO-8859-1" in appnode.tra and then restarting the appnode.

Issue/Introduction

For this error, Under Debug Configuration>Arguments>VM Arguments: Please append "-Dfile.encoding= ISO-8859-1" at the end of the existing value.
