[JIRA-67] TsFile example codes for reading data error [fixed]

[Xiangdong Huang <sa...@gmail.com>]

Hi,

This is an issue for TsFile users who follow the codes under tsfile/example.

tsfile/example/src/main/java/org/apache/iotdb/tsfile/TsFileSequenceRead has
a bug:

if the data is Float with RLE encoding, when we read data by using this
class, an exception will occur if there are more than 2 pages in a chunk.

It is because that for each page, we need to either call
`valueDecoder.reset()` or generate a new value decoder. However, the
example java file call neither.

The JIRA adderss:
https://issues.apache.org/jira/projects/IOTDB/issues/IOTDB-67?filter=allopenissues

It has been fixed in:

https://github.com/apache/incubator-iotdb/pull/113

Best,
