Hello Team,   We are planning to Impala UDFs and UDAs. To try things out we started by exploring the examples given in the cloudera github repo.   After building the .so file using the make utility when I try to create the function using the following   create function has_vowels (string) returns boolean location '/user/hive/udfs/libudfsample.so' symbol='HasVowels';       We are getting the following error   ERROR: AnalysisException: Could not load binary: /<hdfs_path>/udfs/libudfsample.so Unable to load /var/lib/impala/udfs/libudfsample.9909.1.so dlerror: /opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib/impala/lib/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /var/lib/impala/udfs/libudfsample.9909.1.so)     Following are the error logs   org.apache.impala.common.AnalysisException: Could not load binary: /user/parth.khatwani/udfs/libudfsample.so Unable to load /var/lib/impala/udfs/libudfsample.9909.1.so dlerror: /opt/cloudera/parcels/CDH-6.3.2-1.cdh6.3.2.p0.1605554/lib/impala/lib/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /var/lib/impala/udfs/libudfsample.9909.1.so) at org.apache.impala.catalog.Function.lookupSymbol(Function.java:442) at org.apache.impala.analysis.CreateUdfStmt.analyze(CreateUdfStmt.java:92) at org.apache.impala.analysis.AnalysisContext.analyze(AnalysisContext.java:451) at org.apache.impala.analysis.AnalysisContext.analyzeAndAuthorize(AnalysisContext.java:421) at org.apache.impala.service.Frontend.doCreateExecRequest(Frontend.java:1285) at org.apache.impala.service.Frontend.getTExecRequest(Frontend.java:1252) at org.apache.impala.service.Frontend.createExecRequest(Frontend.java:1222) at org.apache.impala.service.JniFrontend.createExecRequest(JniFrontend.java:167) I1009 02:42:52.638576 15136 status.cc:124] 3c48433373076c77:30eff6ff00000000] AnalysisException: Could not load binary: /user/parth.khatwani/udfs/libudfsample.so Unable to load /var/lib/impala/udfs/libudfsample.9909.1.so   I am unable to figure out what's wrong here.     Regards Parth ...

Hello Team, We are using Impala to query data stored as parquet on s3. This has been an awesome feature. Recently Amazon S3 has announced a new feature called S3 Select  which helps in speeding up the column projection when querying data stored on S3. As of now Hive and Presto support  S3 select push down. Is Impala going to support S3 select push downs?   Parth ... View more

Hello Team,     We were planning to implement Role-Based-Access-Control(RBAC) for our impala tables we tried Sentry but there is a prerequisite of installing Kerberos which we don't want to use. So Apache Ranger is the other option we have but the latest CDH version 6.3 has Impala 3.2 which does not support Ranger. So just wanted to if there is going to be release of new CDH bundle which will have Impala 3.3.0 and support for ranger? What will be approximate release date of the new CDH bundle?       Regards Parth ... View more

Hello Team,   We are planning to use Sentry for implementing authorization for Impala Tables. In prerequisites for installing Sentry last point suggest to implement Kerberos authentication but point number 6 mentions that either Kerberos or LDAP is required. This is a bit confusing, can you help in clarifying if it is necessary to implement kerberos authentication for Configuring Sentry.     Regards Parth    ... View more

Hi Team,   Greetings!   There was a need to move the kudu installation from my current cluster of AWS machines to new cluster of  AWS Machines. So I did the following steps. Took the back/sanpshot of disk haivng the kudu data Directory. Installed CDH and kudu on the new AWS cluster and attached the Disk from the older cluster to the newer one. After the installation I checked for kudu health in Cloudera Manager, kudu cluster was healthy and all new tablet servers were running fine along with master. when I ran the ksck command all except few the tables were in CONSENSUS_MISMATCH state Logs suggest the that master is still trying to refer to the tablet servers which is having IP of older machines. Can anybody help in pointing out why this is happening.     Regards Parth   ... View more
