I have a MiniFi process that does site-to-site with a NiFi 1.6. The MiniFi 0.1.0 works just fine connecting to the Upgraded Nifi 1.6. Now I'm upgrading MiniFi and I'm unable to get any data to flow from MiniFi 0.4.0 to NiFi.1.6. I see no errors in the NiFi log. and the only error I see in MiniFi logs are the following: 2018-05-08 14:52:12,535 WARN [Timer-Driven Process Thread-2] o.a.n.c.t.ContinuallyRunConnectableTask RemoteGroupPort[name=svc_perf_team_port01,targets=https://abe-hadoop-nifi01.local:8181/nifi] Administratively Pausing fo 10 seconds due to processing failure: java.lang.RuntimeException: java.lang.NoSuchMethodError: org.apache.http.impl.client.HttpClientBuilder.setSSLContext(Ljavax/net/ssl/SSLContext;)Lorg/apache/http/impl/client/HttpClienBuilder;

Sorry I did not get this to work in xQuery. I ended up using XSLT to do the transformation.

I'm hoping someone can point me in the right direction. I have a SimpleKeyValueLookupService configured with some sample type I'm attempting to lookup. The way I understand it so far (from all the searches I've done) is in the LookUpAttribute I create a Dynamic Property of 'key' and set it's value to be in my case ${column_name}. So my question is where does the result get returned into?

I did test out the connectivity and the Oracle port is working and the DB is up. However I was using a newest driver (ojdbc7.jar), I'm going to fall back to the previouns version whech was working on the other host.

I have moved NiFi from a Windows platform to Linux and installed NiFi 2.0.1, I've also install ojdbc7.jar in the NiFi lib directory (Yes NiFi was restart). I've exported the windows template and imported into the Linux NiFi. I'm testing this new configuration, however I'm getting the following error: 2016-12-16 12:05:57,178 ERROR [Timer-Driven Process Thread-10] o.a.n.p.standard.ConvertJSONToSQL ConvertJSONToSQL[id=89164c79-43c8-4067-4859-cfeab7df7c70] ConvertJSONToSQL[id=89164c79-43c8-4067-4859-cfeab7df7c70] failed to process due to

I have a NiFi host doing ETL processing outside the Hadoop Cluster. The cluster is secured using Knox/Ranger and the only ports open are ssh to the Hadoop Edge Nodes, and Kafka queue. My question is what are the best options to write data into either HBase or Hive? Ideas I have are: Deploy a NiFi inside the cluster do a site to site (requires opening a firewall port) From NiFi write to the Kafka queue, and from inside the cluster write a java process to pull from the queue and output the data to the target (HBase or Hive) Any other sugestions?

I have a JSON array that I'm attempting to input to ConvertJSONToSQL, however I'm getting the following error: "None of the fields in the JSON map to the columns defined" I would like the process to be dynamic rather than use the AttributesToJSON process. Is that possible? My Table does have the EndTime, H1526728411, etc, columns. My JSON looks like: {
"Table":{
"TableName":"HH_CELL_VQI",
"EndTime":"2016-07-12T05:30:00-06:00",
"H1526728411":"0",
"H1526728412":"0",
"H1526728413":"0",
"H1526728414":"0",
"H1526728415":"0",
"H1526728416":"0",
"H1526728417":"0",
"H1526728418":"0",
"H1526728419":"0",
"H1526728420":"0"
}

I have a flow that works on my desktop and I would like to move it to a single server that has 16 cores. My question is there anything I need to configure in NiFi to light up all the cores. I see documentation on clustering servers, which doesn't apply to me, or does NiFI use everything available, which is the behavior I'm looking for?

Wow, didn't know the xQuery could do this. Based on quick research it appears that fn:tokenize might be just what I'm looking for. I'll have to play with this to see if I can this to work.
