Sahil Takiar updated IMPALA-8117:
---------------------------------
Description:
The code for {{KuduCatalogOpExecutor.validateKuduTblExists}} is:
{code:java}
KuduClient kudu = KuduUtil.getKuduClient(masterHosts);
try {
kudu.tableExists(kuduTableName);
} catch (Exception e) {
// TODO: This is misleading when there are other errors, e.g. timeouts.
throw new ImpalaRuntimeException(String.format("Kudu table '%s' does not
exist " +
"on master '%s'", kuduTableName, masterHosts), e);
}
{code}
The issue is that {{kudu.tableExists}} returns {{true}} if the table exists,
{{false}} if it does not. So this method does not actually check if the table
exists.
I went through the rest of the code in {{KuduCatalogOpExecutor}} and it looks
like all other uses of {{kudu.tableExists}} properly check the return value of
the method.
