I am trying to run the sample add function in impala udf-samples.cc.
I got the prerequisites done.
got the build using make.
copied the file "libudfsample.so" to hadoop fs
While running create function using that location, I get this error. Any solution please.
[hdp-stage-dn-stage101.bo.shopzilla.seastg:21000] > create function udf_add(int, int) returns int location '/data/dw/impala_udfs/libudfsample.so' symbol='AddUdf'; Query: create function udf_add(int, int) returns int location '/data/dw/impala_udfs/libudfsample.so' symbol='AddUdf' ERROR: AnalysisException: Could not load binary: /data/dw/impala_udfs/libudfsample.so Unable to load /var/lib/impala/udfs/libudfsample.8434.0.so dlerror: /opt/cloudera/parcels/CDH-5.14.2-1.cdh5.14.2.p0.3/lib/impala/lib/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /var/lib/impala/udfs/libudfsample.8434.0.so)
Do we need to install anything on the impala servers. There was no mention of it in the UDF document.

I am looking to upgrade impala 3.1 on cloudera 5.14.
current version is "Impala Shell v2.11.0-cdh5.14.2"
Are there any software dependencies to lookout for. Any direction / help is much appreciated.
Could not get much help on search with respect to software dependencies like hadoop version etc. or any adjustments to be made to cloudera v5.14.
Most of the impala requsites talk about hardware / Hive metastore.
