FoxNo2 opened a new issue #1187:
URL: https://github.com/apache/incubator-iotdb/issues/1187
使用IoTDB的 0.10.0-SNAPSHOT版本.
IoTDB无数据时,访问IP:8181可以正常显示监控网页,当写入数据后,再次访问,网页报出500异常.
java.lang.NullPointerException
at
org.apache.iotdb.db.metrics.ui.MetricsPage.sqlRow(MetricsPage.java:120)
at
org.apache.iotdb.db.metrics.ui.MetricsPage.render(MetricsPage.java:83)
at
org.apache.iotdb.db.metrics.server.QueryServlet.doGet(QueryServlet.java:42)
查看MetricsPage.java的第120行:
```java
+ "<td>" + (errMsg.equals("") ? "== Parsed Physical Plan ==" : errMsg)
```
是否为此处errMsg为NULL导致,为何写入数据后会报出异常?
