Description

During Metrics tests repairing test org.apache.ignite.igfs.Hadoop1DualAbstractTest#testMetricsBlock revealed the following problem:
org.apache.ignite.hadoop.fs.v1.IgniteHadoopFileSystem#convert(org.apache.ignite.igfs.IgfsFile) method treats groupBlockSize as blockSize for Hadoop FileStatus. groupBlockSize can be several times larger than blockSize, so blockSize in status gets different to that in original IgfsFile .

changing file.groupBlockSize() to file.blockSize() fixes problem in metrics tests, but creates problems in Hadoop tests that are bound to splits calculation, since split calculation related to blockSizes.

Need to
1) clarify if the treatment of groupBlcokSize was intentional.
2) fix either metrics tests or Hadoop tests.
