In this case, you will need to either ensure that your schemas are the same or only select columns that share schema.</p> + +<p><strong>Timestamps and Timezones other than UTC</strong> </p> + +<p>Symptoms: Issues with timestamp and timezone. Illegal instant due to time zone offset transition (America/New_York)</p> + +<p>Solution: Convert data to UTC format. You are most likely trying to import date and time data that is encoded one timezone in a different timezone. Drillâs default behavior is to use the systemâs time for converting incoming data. If you are providing UTC data and your Drillbit nodes do not run with UTC time, youâll need to run your JVM with the following system property:</p> +<div class="highlight"><pre><code class="language-text" data-lang="text"> -Duser.timezone=UTC +</code></pre></div> +<p><code>http://www.openkb.info/2015/05/understanding-drills-timestamp-and.html</code> </p> + +<p><strong>Unexpected ODBC issues</strong> </p> + +<p>Symptom: ODBC errors.</p> + +<p>Solution: Make sure that the ODBC driver version is compatible with the server version. +Turn on ODBC driver debug logging to better understand failure. </p> + +<p><strong>Connectivity issues when connecting via ZooKeeper for JDBC/ODBC</strong> </p> + +<p>Symptom: Client cannot resolve ZooKeeper host names for JDBC/ODBC.</p> + +<p>Solution: Ensure that Zookeeper is up and running. Verify that Drill has the correct drill-override.conf settings for the Zookeeper quorum.</p> + +<p><strong>Metadata queries take a long time to return</strong> </p> + +<p>Symptom: Running SHOW databases/schemas/tables hangs (in general any information_schema queries hang).</p> + +<p>Solution: Disable incorrectly configured storage plugins or start appropriate services. Check compatibility matrix for the appropriate versions. </p> + +<p><strong>Unexpected results due to implicit casting</strong> </p> + +<p>Symptom: rill implicitly casts based on order of precedence.</p> + +<p>Solution: Review Drill casting behaviors and explicitly cast for the expected results. See <a href="/docs/handling-different-data-types/">Data Types</a>.</p> + +<p><strong>Column alias causes an error</strong> </p> + +<p>Symptom: Drill is not case sensitive, and you can provide any alias for a column name. However, if the storage type is case sensitive, the alias name may conflict and cause errors.</p> + +<p>Solution: Verify that the column alias does not conflict with the storage type. See <a href="/docs/lexical-structure/#case-sensitivity">Lexical Structures</a>. </p> + +<p><strong>List (arrays) contains null</strong> </p> + +<p>Symptom: UNSUPPORTED_OPERATION ERROR: Null values are not supported in lists by default. Please set store.json.all_text_mode to true to read lists containing nulls. Be advised that this will treat JSON null values as a string containing the word 'null'.</p> + +<p>Solution: Change Drill session settings to enable all_text_mode per message.<br> +Avoid selecting fields that are arrays containing nulls.</p> + +<p><strong>SELECT COUNT (*) takes a long time to run</strong> </p> + +<p>Solution: In come cases, the underlying storage format does not have a built-in capability to return a count of records in a table. In these cases, Drill will do a full scan of the data to verify the number of records.</p> + +<p><strong>Tableau issues</strong> </p> + +<p>Symptom: You see a lot of error messages in ODBC trace files or the performance is slow.</p> + +<p>Solution: Verify that you have installed the TDC file shipped with the ODBC driver. </p> + +<p><strong>Group by using alias</strong> </p> + +<p>Symptom: Invalid column.</p> + +<p>Solution: Not supported. Use column name and/or expression directly. </p> + +<p><strong>Casting a Varchar string to an integer results in an error</strong> </p> + +<p>Symptom: </p> +<div class="highlight"><pre><code class="language-text" data-lang="text"> SYSTEM ERROR: java.lang.NumberFormatException +</code></pre></div> +<p>Solution: Per the ANSI SQL specification CAST to INT does not support empty strings. If you want to change this behavior, you can set Drill to use the cast empty string to null behavior. This can be done using the drill.exec.functions.cast_empty_string_to_null SESSION/SYSTEM option. </p> + +<p><strong>Unexpected exception during fragment initialization</strong> </p> + +<p>Symptom: The error occurred during the Foreman phase of the query. The error typically occurs due to the following common causes: </p> + +<ul> +<li>Malformed SQL that passed initial validation but failed upon further analysis</li> +<li>Extraneous files in query directories do not match the default format type</li> +</ul> + +<p>Solution: Enable the verbose errors option and run the query again to see if further insight is provided. </p> + +<p><strong>Queries running out of memory</strong> </p> + +<p>Symptom: </p> +<div class="highlight"><pre><code class="language-text" data-lang="text"> RESOURCE ERROR: One or more nodes ran out of memory while executing the query. +</code></pre></div> +<p>Solution: </p> + +<ul> +<li>Increase the amount of direct memory allotted to Drill</li> +<li>If using CTAS, reduce the planner.width.max_per_node setting</li> +<li>Reduce the number of concurrent queries running on the cluster using Drill query queues</li> +<li>Disable hash aggregation and hash sort for your session</li> +<li>See <a href="/docs/configuration-options-introduction/">Configuration Options</a><br></li> +</ul> + +<p><strong>Unclear Error Message</strong> </p> + +<p>Symptom: Cannot determine issue from error message.</p> + +<p>Solution: Turn on verbose errors. </p> +<div class="highlight"><pre><code class="language-text" data-lang="text"> alter session set `exec.errors.verbose`=true; +</code></pre></div> +<p>Determine your currently connected drillbit using select * from sys.drillbits.
