Hi, see this form ambari minor upgrade: https://docs.hortonworks.com/HDPDocuments/Ambari-2.7.3.0/bk_ambari-upgrade/content/checkpoint_hdfs.html Do you have hdfs whit HA enabled?

Hi @jessica moore, see this https://github.com/apache/ambari/blob/trunk/ambari-server/docs/api/v1/index.md

Yes, it works. Thanks

Hi all, HDP 2.6.3 with Hive 2. I have enabled the ACID transaction; when run the compaction I have seen max 3 job on YARN queue. I tried to launch manually more than 3 compaction, but they are execute 3 at a time. Is there a parameter to set the max concurrent compaction jobs? Thancks in advance

in your place I would have: convert record to JSON not to CSV use EvaluateJsonPath to set the attribute from the JSON in the contentFile use updateAttribute to transform datetime and user use ReplaceText to replace all contentFile with the altered attribute write the contentFile to FS

sorry for the mistake, obviously the operation is performed on the attribute, not on the FlowFile. So you must first set the values you need in the attributes and then transform them. Thanks @Matt Clarke

Try to execute tailf /proc/<pid_execution_script>/fd/2 pid_execution_scipt --> on the server where run NiFi you look for the process id, not the pid of NiFi service. Sometimes ExecutionScript ddoes not recivie the termination of the script. I do not know how to solve this 😞

isoardi · ‎04-23-2018

you must change the attribute on which to perform the transformation. I never used the GrokReader, but I believe you have to change ts to in timestamp in the EL string

isoardi · ‎04-23-2018

Hi @Wojtek, I believe the problem is that the format() function works only with numbers. Your timestamp has a '.' (dot) which makes it interpret as a string. To solve the problem I have adopted the following EL un a updateAttribute processor: ${ts:substringBefore('.'):append(${ts:substringAfter('.')}) :toNumber():format('MM/dd/yyyy HH:mm:ss.SSS') } ts attribute contains this value 1518442283.483 the result is 02/12/2018 13:31:23.483 I hope I have been of help

I have a cluster with 7 NiFi nodes. After a node crash, on restart, NiFi could not find the file /usr/hdf/current/nifi/conf/keystore.jks and truststore.jks I have re-created the files with tls-toolkit.sh client -c tp-hostname.domain.com -t passwordPassword -p 10443 In Ambari config the keystore and truststore pasword are empty. When I start the NiFi services Ihave: Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'protocolSocketConfiguration': FactoryBean threw exception on object creation; nested exception is java.io.IOException: Keystore was tampered with, or password was incorrect at org.springframework.beans.factory.support.FactoryBeanRegistrySupport.doGetObjectFromFactoryBean(FactoryBeanRegistrySupport.java:175) at org.springframework.beans.factory.support.FactoryBeanRegistrySupport.getObjectFromFactoryBean(FactoryBeanRegistrySupport.java:103) at org.springframework.beans.factory.support.AbstractBeanFactory.getObjectForBeanInstance(AbstractBeanFactory.java:1585) at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:317) at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:197) at org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveReference(BeanDefinitionValueResolver.java:351) ... 78 common frames omitted Caused by: java.io.IOException: Keystore was tampered with, or password was incorrect at sun.security.provider.JavaKeyStore.engineLoad(JavaKeyStore.java:780) at sun.security.provider.JavaKeyStore$JKS.engineLoad(JavaKeyStore.java:56) at sun.security.provider.KeyStoreDelegator.engineLoad(KeyStoreDelegator.java:224) at sun.security.provider.JavaKeyStore$DualFormatJKS.engineLoad(JavaKeyStore.java:70) at java.security.KeyStore.load(KeyStore.java:1445) at org.apache.nifi.io.socket.SSLContextFactory.<init>(SSLContextFactory.java:65) at org.apache.nifi.cluster.protocol.spring.SocketConfigurationFactoryBean.getObject(SocketConfigurationFactoryBean.java:45) at org.apache.nifi.cluster.protocol.spring.SocketConfigurationFactoryBean.getObject(SocketConfigurationFactoryBean.java:30) at org.springframework.beans.factory.support.FactoryBeanRegistrySupport.doGetObjectFromFactoryBean(FactoryBeanRegistrySupport.java:168) ... 83 common frames omitted Caused by: java.security.UnrecoverableKeyException: Password verification failed at sun.security.provider.JavaKeyStore.engineLoad(JavaKeyStore.java:778) ... 91 common frames omitted In nifi.properties I have: nifi.security.keyPasswd= nifi.security.keystore=/usr/hdf/current/nifi/conf/keystore.jks nifi.security.keystorePasswd= nifi.security.keystoreType=jks nifi.security.needClientAuth=False nifi.security.ocsp.responder.certificate= nifi.security.ocsp.responder.url= nifi.security.truststore=/usr/hdf/current/nifi/conf/truststore.jks nifi.security.truststorePasswd= nifi.security.truststoreType=jks nifi.security.user.authorizer=ranger-provider nifi.security.user.login.identity.provider= nifi.sensitive.props.additional.keys= nifi.sensitive.props.algorithm=PBEWITHMD5AND256BITAES-CBC-OPENSSL nifi.sensitive.props.key=sdlkjdslkjsdlkjdjjd||xyGZZ+R3FO04BxcUHSL5U6+OGqtQQevXbFfecQ nifi.sensitive.props.key.protected=aes/gcm/256 nifi.sensitive.props.provider=BC On other NiFi nodes I have an encrypted password in nifi.properties, but the truststore and the keystore has an empty string as a password.

Hi guys, I see surfing the internet that the max numbers of files stored in HDFS is equals at Integer.MAX_VALUE of JVM. Any confirmation that the maximum number of files is this (2.147.483.647)?

Hi @Petra Zimmer, You can test the repo with wget from your Ambari server node: wget <HDP-Base-URL>/repodata/repomd.xml wget <HDP-UTILS-Base-URL>/repodata/repomd.xml If one of them is wrong, or not accessible then the upgrade will fail.

It is not totally true: with NiFi you can get "aloha.csv" from different source (web, local file, HDFS, DB, twitter, ...), enrich the data (for example you can merge with "byebye.csv") or to modify the data, and save data (to hive in different ways, to hdfs, to local file, ...). If you eant to see the personalityof twitter user, you can not use NiFi to calculate it. For this you can use spark
