Thanks Mark, so this is a quick way to search for 'expected' components and get an actual ID handle to work with them next. My use case is programmatic flow control through an API. ... View more

Very old topic, but still valid. Do I understand it right, if we have no provenance enabled, it makes no sense to have the content repo archive enabled? If both is enabled, how can we recover a single flow, via the provenance window? ... View more

Guys be aware that the oracle website needs you to accept the license and you have to put it in you command line. the following code is working perfectly. enjoy # sudo wget --no-cookie --no-check-certificate --header "Cookie:gpw_e24=http%sA2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u92-b14/jdk-8u92-linux-x64.tar.gz?AuthParam=1465316438_f262c7659515d89274633588ae8f73ca # mkdir /usr/java # mv jdk-8u92-linux-x64.tar.gz /usr.java/jdk-8u92-linux-x64.tar.gz # tar zxvf jdk-8u92-linux-x64.tar.gz # ln -s /usr/java/jdk1.8.0_92 /usr/java/default # export JAVA_HOME=/usr/java/default # export PATH=$JAVA_HOME/bin:$PATH ...

Hey Andrew, I'm having the same issue. Did you find any fixes for this? It's great it can be changed without a restart... but having to come back in and set this anytime Solr or the server itself is restarted isn't great. 🙂 EDIT: Help from Hortonworks support pointed out that in log4j.properties (either in Ambari if your Solr Cloud is managed there, or directly on server if not) you can adjust the following line from: log4j.rootLogger=INFO, file, CONSOLE Changed to: log4j.rootLogger=WARN, file, CONSOLE That will allow it to retain this change on Solr startup. ...
