Seeing "file not found" java i/o errors during tUniqrow, tMap, and tMySQLBulkExec

[tmaglio_td]

Hi,

  I'm  on Talend version 6.3.1, patch version 20190516_0928.

I have a series of jobs that make use of different components: tMap, tUniqueRow, and tMysqlBulkExec.

These jobs can run hundreds of times each day. 

I am seeing sporadic failures stemming from the temporary files used by these components going missing.

The error is "java.io.FileNotFoundException:<directory>tUniqRow_2_TEMP_0 (No such file or directory)"

The choice to use temp files in these components is because at times the data sets are too large to fit into memory. 

However, it seems like using temp files and disk presents its own problems.

Has anyone else seen this behavior or have any suggestions on managing it?

Any help would be appreciated.

Thank you
