title: Table was modified while operation was in progress, aborting execution in impala
body: <p>We’re trying to run some set of queries on impala in parallel. Both these sets work on individual set of tables. However, intermittently, they give warning: “Table was modified while operation was in progress, aborting execution.”  We tried refreshing the tables, metadata. Still finding the same issue. Any suggestions why it occurs and possible solution to avoid it? </p>
