[jira] [Comment Edited] (IMPALA-9908) SHOW PARTITIONS on a kudu
backed impala table return NULL on Replicas
[ https://issues.apache.org/jira/browse/IMPALA-9908?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17148154#comment-17148154 ]

------------------------------------------------------------------
From debugging, I can see schema in hs2 protocol is transferred from
impala::TYPE_INT to
{apache::hive::service::cli::thrift::TTypeEntry & }
apache::hive::service::cli::thrift::TTypeId::INT_TYPE,
while in beeswex protocol it's transferred from
Impala::TPrimitiveType::INT to
{Apache::Hadoop::Hive::FieldSchema & }
Type = “int”
