Sivaprasanna Sethuraman resolved NIFI-5876. ------------------------------------------- Resolution: Not A Bug Fix Version/s: 1.8.0 This is not an issue. The forward slash & backward slash is a known matter. \ is considered special in Windows world. You can either use '/' or escape '\' i.e. \\. Ex: C:\\bin\\hadoop-2.7.1\\etc\\hadoop\\core-site.xml > PutHDFS executes with SUCESS, although exception in logs and no file saved. > --------------------------------------------------------------------------- > > Key: NIFI-5876 > URL: https://issues.apache.org/jira/browse/NIFI-5876 > Project: Apache NiFi > Issue Type: Bug > Affects Versions: 1.7.1 > Environment: NiFi on Windows 10 > Reporter: Jan-Henrik Preuss > Priority: Minor > Labels: windows > Fix For: 1.8.0 > > > Issue: > PutHDFS executes with SUCESS, although exception in logs and no file saved. > Solution: > Propagate exception to UI (with FAILURE status). > Steps to reproduce > # This error applies to an installation of Nifi on a MS Windows system > # Make your own application properties file (e.g. myapp-nifi.properties) and > link it in the main nifi.properties file (with property > “nifi.variable.registry.properties=<mypath>/myapp-nifi.properties”) > # Enter a new property > “hadoop_conf=C:\bin\hadoop-2.7.1\etc\hadoop\core-site.xml,C:\bin\hadoop-2.7.1\etc\hadoop\hdfs-site.xml” > in myapp-nifi.properties (Hadoop is installed in the corresponding directory) > # The backslashes of the directory path of the configuration are the > important thing to look at > # Restart Nifi to take the configuration change into account > # Open the properties configuration of the PutHDFS processor > # Set the " Hadoop Configuration Resources" to the variable key of the > external property: ${hadoop_conf}. > # Execute the flow/processor with some path and filename to put into HDFS. > # Processor executes with SUCCESS > # Log file shows "java.lang.reflect.InvocationTargetException: null" > # No file is written into HDFS > Example external properties file: > > hadoop_conf=C:\bin\hadoop-2.7.1\etc\hadoop\core-site.xml,C:\bin\hadoop-2.7.1\etc\hadoop\hdfs-site.xml > Setting the path value directly in the PutHDFS processor with the "\" path > can be used and executes correct (no error, file is stored in HDFS). > Workaround: > Replace windows backslah "\" with "/" in the external property file (e.g. > hadoop_conf=C:/bin/hadoop-2.7.1/etc/hadoop/core-site.xml,C:/bin/hadoop-2.7.1/etc/hadoop/hdfs-site.xml). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
